I would like a better way to manage all the warnings. I don't particularly
like the warnWhenAmbig=false flag. For one it doesn't work for all the
cases I want it for.
I think a companion tool could be better at annotating error messages and
presenting new ones/hiding old ones, etc.
An ANTLR Cookbook would be quite handy too, and could be built on top of the
existing examples, and my C grammar :)
Of course there's a slew of tree things but Loring's got that covered from
the design cabal.
Interactive parsers are not so fun with ANTLR 2.
I would like to be able to trace a Token all the way back to file offsets so
I could modify files in place, not have to regenerate them entirely. That's
not so easy with Unicode.

Folks,
In preparation for the ANTLR 3.0 whitepaper, I need to start writing
down everything that annoys me about ANTLR 2.0. I have started another
"blog" document:
http://www.antlr.org/blog/antlr3/antlr2.bashing.tml
Feel free to send in your pet peeves to me or to this list. I will try
to add to this file.
I can hear John Mitchell now: "predicate hoisting!" ;)
