[antlr-interest] please help on simple parser antlr v3

[Thomas Brandon]

Wouldn't that mean with the above lexer if you tried to use WS in your
parser to match an LF that nothing would match but you would have got
no warnings (not an issue here as they're all skipped)? Or what if you
had actions in the WS rule (other than skip)? Unless I'm
misunderstanding that seems like it could lead to rather annoying
grammar problems.
