Hi!
Consider the following grammar
topLevel : expr;
expr : mult_expr ( (PLUS | MINUS) mult_expr)*;
mult_expr : primary_expr ((MULT | DIV) primary_expr)*;
primary_expr: ID | (LPAREN ID RPAREN);
FOr this simple grammar if I give input as (1+2)) then even though
it is a case of unmatched paranthesis there is no exception
generated. The problem is that RPAREN is coming as a valid expected
token in one of the rule. Could you please tell me if there is a bug
somethere??
Thanks,
Sanjiv
