[antlr-interest] Selective unhiding of HIDDEN channel

[Bill Andersen]

Hi Folks

I have a parser grammar, part of which has to pay attention to newlines, and part of which can ignore them.  Not my favorite design for a grammar, but I'm stuck with it.

Normally, I would like to dump newlines to the HIDDEN channel, but selectively "turn on" the hidden channel to pay attention to newlines.  Is there any good way to do this?

Thanks in advance.
