Yeah, but you can't do this in C++ though:
class D : B {
this()

writeln("derived is only now complete");
super();

I find the ability to control the construction order far more
important than virtual calls for base constructors.
You could do it in old C++ compilers, and some have a permissive switch
that allows you to do it, but you should not do it. It leads to
incorrect initialization and breaks encapsulation (unsound typing).
Forcing construction order is a Good Thing.
You can do it in C++ via initializers too, just not as useful. D still
enforces sound construction.
