I think that this could be a good feature. You can get the qualified name with get_class() if you have an instant, or with __CLASS__ in your class methods, but you can't explicitly convert an unqualified name into qualified. However this wasn't a big problem for me, because every reference is used as a fully qualified name, so I never had to convert between them. But this could be a good addition to the namespace features. Tyrael
