+1 for that, never understood the reason against this given that 
we live in the 20ies now.
If performance is the problem, you wouldn't choose virtual 
dispatch anyway.
If safety is the problem, then disambiguation by scoping is the 
solution.

Yes, but interfaces can't have fields. I find D should better 
interop with C++ classes without the `extern` sh!t, and 
supporting multiple inheritance should work out of the box.

Who wants to manually create thousands of classes to interop with 
a c++ framework?
