You don't need it as a 1st-class D concept though. Just implement the 
basics of the C++ object model in D, similar to what I did for 
Objective-C, and let people define their own extern(C++) classes with 
no base class. Bonus if it's binary compatible with the equivalent C++ 
class. Hasn't someone done that already?
