That's exactly what I was looking for. I think it means that we don't
need to have a 1-to-1 mapping of C and C++ stub instances. So, we
shouldn't need that g_object_set_qdata()-like thing anymore. That should
have been obvious to me - this is CORBA, after all.

More thinking aloud, in case anybody cares or objects:

And I see no great advantage in inheriting from CORBA_Object, so I'll
look at making the CORBA_Object a member of CORBA::Object instead. That
conveniently solves the hidden CORBA_Object declaration issue too.
