This is nonsense. You cannot assign an interface to a class.
A class IMPLEMENTS an interface, it is not an interface.
Ok, its nonsense. I said it already works with my patch, but I guess you
know it better. So my example down there doesn't work (with patch). You
should know.
I (; can't ;) transfer from one interface to other back to object and to
3rd interface. I just imagine my results.
Tell me, what is
obj := a;
supposed to DO ? A class has a set of methods. Some of these methods form
the VMT of an interface. What your code does, is say
"don't use your VMT methods, use these instead' ?
