There is a warning, maybe there should be a correct way to avoid it ?


./antlr.sh BugType.g
warning(105): BugType.g:22:4: no lexer rule corresponding to token: IF

=======================

grammar A;

tokens {
	IF;
}

WORD: 'a' { $type=IF; } ;

document	:	IF;

========================

I used to change tokens { .. } section into this to remove warning:

IF: {false}? .;

But feels dirty.
