STUFF

* lexer

* parser

* desugar
   - get rid of immediately applied functions:

             (function () { /* ... */ })();

         can become nothing but:

             { /* ... */ }

         if there are no 'vars' inside it.  if there are, we hoist the
         vars to the toplevel of the function and convert them to
         lets, then replace it with the { }

* lambda lifting

* optimizations

* ffi

  - we need some sort of DSL for external C-linkage functions.  bonus points for a syntax that allows objc messages as well.
    maybe something like:

  @extern void print_internal_i32 (@i32(theInt))
  @extern void print_internal_d64 (@d64(theDouble))
  @extern void print_internal_string (@string(theString))

  function print(theObj) {
    if (theObj === null)
      print_internal_string ("null");
    else if (typeof(theObj) == "undefined")
      print_internal_string ("undefined");
    else if (typeof(theObj) == "object")
      print_internal_string (theObj.toString());
  }
