[antlr-interest] '%' in action (bug?)

[Junkman]

Greetings,

The following grammar generates invalid string template error (146):

---------------------------------
grammar Test;

@lexer::members {

	int x = 1234 \% 1;

}


TOKEN : 'bogus' ;

stmt	:	
	( . )+
	;

---------------------------------

For @lexer::members action, the modulo operator ('%') causes the error -
escaping with backslash doesn't help.

No problem for @parser::members.

A bug?
