[antlr-interest] ANTLR 3.0b5 problem with predicates

[Shmuel Siegel]

Right, the sources where I found those lines are antlr 2 grammars. My
question is how do I do the same thing in antlr3 for situations where
greedy=false doesn't suffice. Antlr3 generates unusable code for the
same constructs.

You're talking about V2 grammars right?
