the parens in this statement might be moot Do you mean that the () in (A|B) is kinda bad because it captures A or B as well as acting to place a limit around A|B? If so you can (?:A|B) instead which groups A|B, but doesn't capture the match. If you mean something else, perhaps you would like to spell it out for us?
