Like I said in chat, these are NOT the same thing. The C++
Derived is a *sibling* class, not a parent, child, nor binding to
the D Derived.
All your attempts to pass one off as the other is problematic. If
you want to bind to the C++ derived, don't provide any bodies for
the functions - just bind. If you want to inherit from it, you
must first declare the binding in D, then inherit.
