- Loring reminded me just now in a post: I want to be able to reference EOF
  in the lexer as a 'normal' token. uponEOF is a kludge.
- ANTLR should stay a commandline tool (the core functionality for grammar
  inheritance or whatever it should replace I don't care) if it doesn't run
  from a Makefile I'm not interested ;)
- More documentation in the code.
- The lack of warnings/errors for incorrect use of options/constructs
- Not being able to specify a default template errorhandler for the whole
  grammar.

Internal things:
- Internally I'd like a better interface between codegenerator and what is
  now the action parser. (if that's still an issue with the new
  codegen/syntax) The near heuristics now used to do the right thing to
  translate a #treethingy into something sane is a horror.
- Codegen wise I'd like to know more things before I start generating a
  piece of code, so I can cut down on declarations etc. Stuff that does not
  need to be constructed does not cost cpu cycles.
- I dislike the 'all-over-the-place' system used for grammar/file options.
  I'd prefer having the included codegenerators register commandline
  options and handlers in the maintool (and get rid of all the globals for
  them).

That's all I can think of for now..

Cheers,

Ric
