[antlr-interest] How to get ANTLR 3.2 to exit upon first error?

[Kirby Bohling]

You need to repeat some of that for the lexer.  Using the
@lexer::members syntax if you're going to do it as a combined
lexer/parser grammar (I always separate mine to keep my mental working
set smaller).  If you don't do the lexer, you can have a lex error and
recover from it, but this should catch all of the parse errors.
