[antlr-interest] stuff I don't like about ANTLR 2.x

I also hate dealing with ambiguous keywords!

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!" ;)
