 ```ruby
 # Get evens and square each
 someSource

-  .each {|x| puts x.to_s }

 Using RxRuby, you can accomplish the same kind of thing with a push-based collection by changing `each` to `subscribe`.
 
 ```ruby
 someSource
-  .select {|x| x.even? }
-  .map {|x| x * x }
-  .subscribe {|x| puts x.to_s }
+  .select { |x| x.even? }
+  .map { |x| x * x }
+  .subscribe { |x| puts x.to_s }
 ```
