All tokens go to the parser (unless skip() is called in that rule)
on a particular "channel". The parser tunes to a particular channel
so that whitespace etc... can go to the parser on a "hidden" channel.
Static hidden
hidden:number = 99
Anything on different channel than DEFAULT_CHANNEL is not parsed
by parser.
