[antlr-interest] [v3] LITERAL_xxx tokens?

[Anthony Youngman]

Is that defining a variable called IF, or STATIC ... ?

That will blow up a heck of a lot of languages. I guess that's why v2
prefixed everything with LITERAL_ - precisely to prevent explosions when
compiling the grammar.

Note to Ter - not that I have any use for it - might it make sense for
v3 to generate this stuff automatically if asked by a switch - seeing as
people like David have a need for it?

Cheers,
Wol

Now that I think about it more, maybe this is actually a better way to
define a concrete interface between the parser and the application than
all those LITERAL_.. thingies anyway.  Nice to have them both using
STATIC to refer to the same thing, eh?

It'll be a *lot* easier to use IDE-auto-complete from the java side
without that common prefix everywhere too! ;)
