+/**
+ * A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
+ * tasks are specified as parameters to the function, after the usual callback
+ * parameter, with the parameter names matching the names of the tasks it
+ * depends on. This can provide even more readable task graphs which can be
+ * easier to maintain.
+ *
+ * If a final callback is specified, the task results are similarly injected,
+ * specified as named parameters after the initial error parameter.
+ *
+ * The autoInject function is purely syntactic sugar and its semantics are
+ * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
+ *
+ * @name autoInject
+ * @static
+ * @memberOf module:ControlFlow
+ * @method
+ * @see [async.auto]{@link module:ControlFlow.auto}
+ * @category Control Flow
+ * @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
+ * the form 'func([dependencies...], callback). The object's key of a property
+ * serves as the name of the task defined by that property, i.e. can be used
+ * when specifying requirements for other tasks.
+ * * The `callback` parameter is a `callback(err, result)` which must be called
+ *   when finished, passing an `error` (which can be `null`) and the result of
+ *   the function's execution. The remaining parameters name other tasks on
+ *   which the task is dependent, and the results from those tasks are the
+ *   arguments of those parameters.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback, and a `results` object with any completed
+ * task results, similar to `auto`.
+ * @example
+ *
+ * //  The example from `auto` can be rewritten as follows:
+ * async.autoInject({
+ *     get_data: function(callback) {
+ *         // async code to get some data
+ *         callback(null, 'data', 'converted to array');
+ *     },
+ *     make_folder: function(callback) {
+ *         // async code to create a directory to store a file in
+ *         // this is run at the same time as getting the data
+ *         callback(null, 'folder');
+ *     },
+ *     write_file: function(get_data, make_folder, callback) {
+ *         // once there is some data and the directory exists,
+ *         // write the data to a file in the directory
+ *         callback(null, 'filename');
+ *     },
+ *     email_link: function(write_file, callback) {
+ *         // once the file is written let's email a link to it...
+ *         // write_file contains the filename returned by write_file.
+ *         callback(null, {'file':write_file, 'email':'user@example.com'});
+ *     }
+ * }, function(err, results) {
+ *     console.log('err = ', err);
+ *     console.log('email_link = ', results.email_link);
+ * });
+ *
+ * // If you are using a JS minifier that mangles parameter names, `autoInject`
+ * // will not work with plain functions, since the parameter names will be
+ * // collapsed to a single letter identifier.  To work around this, you can
+ * // explicitly specify the names of the parameters your task function needs
+ * // in an array, similar to Angular.js dependency injection.
+ *
+ * // This still has an advantage over plain `auto`, since the results a task
+ * // depends on are still spread into arguments.
+ * async.autoInject({
+ *     //...
+ *     write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {
+ *         callback(null, 'filename');
+ *     }],
+ *     email_link: ['write_file', function(write_file, callback) {
+ *         callback(null, {'file':write_file, 'email':'user@example.com'});
+ *     }]
+ *     //...
+ * }, function(err, results) {
+ *     console.log('err = ', err);
+ *     console.log('email_link = ', results.email_link);

+/**
+ * An "async function" in the context of Async is an asynchronous function with
+ * a variable number of parameters, with the final parameter being a callback.
+ * (`function (arg1, arg2, ..., callback) {}`)
+ * The final callback is of the form `callback(err, results...)`, which must be
+ * called once the function is completed.  The callback should be called with a
+ * Error as its first argument to signal that an error occurred.
+ * Otherwise, if no error occurred, it should be called with `null` as the first
+ * argument, and any additional `result` arguments that may apply, to signal
+ * successful completion.
+ * The callback must be called exactly once, ideally on a later tick of the
+ * JavaScript event loop.
+ *
+ * This type of function is also referred to as a "Node-style async function",
+ * or a "continuation passing-style function" (CPS). Most of the methods of this
+ * library are themselves CPS/Node-style async functions, or functions that
+ * return CPS/Node-style async functions.
+ *
+ * Wherever we accept a Node-style async function, we also directly accept an
+ * [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}.
+ * In this case, the `async` function will not be passed a final callback
+ * argument, and any thrown error will be used as the `err` argument of the
+ * implicit callback, and the return value will be used as the `result` value.
+ * (i.e. a `rejected` of the returned Promise becomes the `err` callback
+ * argument, and a `resolved` value becomes the `result`.)
+ *
+ * Note, due to JavaScript limitations, we can only detect native `async`
+ * functions and not transpilied implementations.
+ * Your environment must have `async`/`await` support for this to work.
+ * (e.g. Node > v7.6, or a recent version of a modern browser).
+ * If you are using `async` functions through a transpiler (e.g. Babel), you
+ * must still wrap the function with [asyncify]{@link module:Utils.asyncify},
+ * because the `async function` will be compiled to an ordinary function that
+ * returns a promise.

+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

-/**
- * A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
- * tasks are specified as parameters to the function, after the usual callback
- * parameter, with the parameter names matching the names of the tasks it
- * depends on. This can provide even more readable task graphs which can be
- * easier to maintain.
- *
- * If a final callback is specified, the task results are similarly injected,
- * specified as named parameters after the initial error parameter.
- *
- * The autoInject function is purely syntactic sugar and its semantics are
- * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
- *
- * @name autoInject
- * @static
- * @memberOf module:ControlFlow
- * @method
- * @see [async.auto]{@link module:ControlFlow.auto}
- * @category Control Flow
- * @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
- * the form 'func([dependencies...], callback). The object's key of a property
- * serves as the name of the task defined by that property, i.e. can be used
- * when specifying requirements for other tasks.
- * * The `callback` parameter is a `callback(err, result)` which must be called
- *   when finished, passing an `error` (which can be `null`) and the result of
- *   the function's execution. The remaining parameters name other tasks on
- *   which the task is dependent, and the results from those tasks are the
- *   arguments of those parameters.
- * @param {Function} [callback] - An optional callback which is called when all
- * the tasks have been completed. It receives the `err` argument if any `tasks`
- * pass an error to their callback, and a `results` object with any completed
- * task results, similar to `auto`.
- * @example
- *
- * //  The example from `auto` can be rewritten as follows:
- * async.autoInject({
- *     get_data: function(callback) {
- *         // async code to get some data
- *         callback(null, 'data', 'converted to array');
- *     },
- *     make_folder: function(callback) {
- *         // async code to create a directory to store a file in
- *         // this is run at the same time as getting the data
- *         callback(null, 'folder');
- *     },
- *     write_file: function(get_data, make_folder, callback) {
- *         // once there is some data and the directory exists,
- *         // write the data to a file in the directory
- *         callback(null, 'filename');
- *     },
- *     email_link: function(write_file, callback) {
- *         // once the file is written let's email a link to it...
- *         // write_file contains the filename returned by write_file.
- *         callback(null, {'file':write_file, 'email':'user@example.com'});
- *     }
- * }, function(err, results) {
- *     console.log('err = ', err);
- *     console.log('email_link = ', results.email_link);
- * });
- *
- * // If you are using a JS minifier that mangles parameter names, `autoInject`
- * // will not work with plain functions, since the parameter names will be
- * // collapsed to a single letter identifier.  To work around this, you can
- * // explicitly specify the names of the parameters your task function needs
- * // in an array, similar to Angular.js dependency injection.
- *
- * // This still has an advantage over plain `auto`, since the results a task
- * // depends on are still spread into arguments.
- * async.autoInject({
- *     //...
- *     write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {

-/**
- * An "async function" in the context of Async is an asynchronous function with
- * a variable number of parameters, with the final parameter being a callback.
- * (`function (arg1, arg2, ..., callback) {}`)
- * The final callback is of the form `callback(err, results...)`, which must be
- * called once the function is completed.  The callback should be called with a
- * Error as its first argument to signal that an error occurred.
- * Otherwise, if no error occurred, it should be called with `null` as the first
- * argument, and any additional `result` arguments that may apply, to signal
- * successful completion.
- * The callback must be called exactly once, ideally on a later tick of the
- * JavaScript event loop.
- *
- * This type of function is also referred to as a "Node-style async function",
- * or a "continuation passing-style function" (CPS). Most of the methods of this
- * library are themselves CPS/Node-style async functions, or functions that
- * return CPS/Node-style async functions.
- *
- * Wherever we accept a Node-style async function, we also directly accept an
- * [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}.
- * In this case, the `async` function will not be passed a final callback
- * argument, and any thrown error will be used as the `err` argument of the
- * implicit callback, and the return value will be used as the `result` value.
- * (i.e. a `rejected` of the returned Promise becomes the `err` callback
- * argument, and a `resolved` value becomes the `result`.)
- *
- * Note, due to JavaScript limitations, we can only detect native `async`
- * functions and not transpilied implementations.
- * Your environment must have `async`/`await` support for this to work.
- * (e.g. Node > v7.6, or a recent version of a modern browser).
- * If you are using `async` functions through a transpiler (e.g. Babel), you
- * must still wrap the function with [asyncify]{@link module:Utils.asyncify},
- * because the `async function` will be compiled to an ordinary function that
- * returns a promise.

-/**
- * Produces a new collection of values by mapping each value in `coll` through
- * the `iteratee` function. The `iteratee` is called with an item from `coll`
- * and a callback for when it has finished processing. Each of these callback
- * takes 2 arguments: an `error`, and the transformed item from `coll`. If
- * `iteratee` passes an error to its callback, the main `callback` (for the
- * `map` function) is immediately called with the error.
- *
- * Note, that since this function applies the `iteratee` to each item in
- * parallel, there is no guarantee that the `iteratee` functions will complete
- * in order. However, the results array will be in the same order as the
- * original `coll`.
- *
- * If `map` is passed an Object, the results will be an Array.  The results
- * will roughly be in the order of the original Objects' keys (but this can
- * vary across JavaScript engines).
- *

- * @method
- * @category Collection
- * @param {Array|Iterable|Object} coll - A collection to iterate over.
- * @param {AsyncFunction} iteratee - An async function to apply to each item in
- * `coll`.
- * The iteratee should complete with the transformed item.

- * @param {Function} [callback] - A callback which is called when all `iteratee`
- * functions have finished, or an error occurs. Results is an Array of the

-/**
- * Run the `tasks` collection of functions in parallel, without waiting until
- * the previous function has completed. If any of the functions pass an error to
- * its callback, the main `callback` is immediately called with the value of the
- * error. Once the `tasks` have completed, the results are passed to the final
- * `callback` as an array.
- *
- * **Note:** `parallel` is about kicking-off I/O tasks in parallel, not about
- * parallel execution of code.  If your tasks do not use any timers or perform
- * any I/O, they will actually be executed in series.  Any synchronous setup
- * sections for each task will happen one after the other.  JavaScript remains
- * single-threaded.
- *
- * **Hint:** Use [`reflect`]{@link module:Utils.reflect} to continue the
- * execution of other tasks when a task fails.
- *
- * It is also possible to use an object instead of an array. Each property will
- * be run as a function and the results will be passed to the final `callback`
- * as an object instead of an array. This can be a more readable way of handling
- * results from {@link async.parallel}.
- *
- * @name parallel
- * @static
- * @memberOf module:ControlFlow
- * @method
- * @category Control Flow
- * @param {Array|Iterable|Object} tasks - A collection of
- * [async functions]{@link AsyncFunction} to run.
- * Each async function can complete with any number of optional `result` values.
- * @param {Function} [callback] - An optional callback to run once all the
- * functions have completed successfully. This function gets a results array
- * (or object) containing all the result arguments passed to the task callbacks.
- * Invoked with (err, results).
- *
- * @example
- * async.parallel([
- *     function(callback) {
- *         setTimeout(function() {
- *             callback(null, 'one');
- *         }, 200);
- *     },
- *     function(callback) {
- *         setTimeout(function() {
- *             callback(null, 'two');
- *         }, 100);
- *     }
- * ],
- * // optional callback
- * function(err, results) {
- *     // the results array will equal ['one','two'] even though
- *     // the second function had a shorter timeout.
- * });

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.
