So I'm not sure it'd be really useful to do more mangling in the tokenizer. At any rate, it won't prevent bison from complaining for shift/reduce (for the first patch) or reduce/reduce (for the second) conflicts. On another note, I don't know why labels are allowed for statement given. break doesn't accept a label, and next/last won't see it if there's one. Vincent.Thread Previous | Thread Next
