Hi.

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.
