[antlr-interest] Channel=HIDDEN In ANTLR 3.0b5, ANTLRworks 1.0b6

[Foolish Ewe]

Thanks Randall:

Sorry that I missed that, I just looked more carefully at the readme and 
must have
missed the leading $.  I thought the $ was needed to access a token or a 
"handle"
bound to a token in the grammar rules, is channel a token or am I 
misunderstanding
the semantics of the leading $?

Regards:

Bill M.
