subclass to base class but not subclass pointer to base class pointer?

Ah, I think I understand know what you meant.
Sure there is no pointer to pointer polymorphism in there.
But I thought, even if D classes are reference types and not 
really compareable to C++ classes, that the compiler could do the 
same implicit cast for pointer of D classes. ;)
