[antlr-interest] Source positions for imaginary tokens

error(114): MySQL.g:2400:4: attribute is not a token, parameter, or return value: token

The rule is like this:

keyword:
	keyword_sp
	(
	| ASCII_SYMBOL
	| BACKUP_SYMBOL
...
	| UPGRADE_SYMBOL
	) { $token->type = IDENTIFIER; }
;

Been there, done that. This seems only to work for lexer rules.
