- remove unnecessary callback dynamics
- stop using dicts to get around javascript's array behavior (assignments to indexes > len(x) autocreate undefined elements)
- docs, of course
- more tests (corner cases, negative cases, larger pages)
__slots__?- keep track of unresolved symbols and proffer a blank schema for introspection/convenience?
- More robust URL helpers
- Add log checking to tests
- Javascript implicitly disregards extra arguments passed to a function, so a lot of dust.js's functions were weird to port. Especially so in the case of code generation. Example: the exists tag takes params, but they're pushed into the stack/context by the time the generated code runs. Nevertheless, the generated js passes them to the Chunk.exists() function, even though it doesn't take them.
