Apart from that they can be freely used, e.g. you could also have a constant called "parent". The special meaning exists in (nearly) any classname context. parent::$foo is just one case. It's just as special if you do new parent() or something like that ;) So I don't think it makes sense to highlight only when followed by :: Nikita
