The key quality for a good OO paradigm is that you can 
independently modify super-classes and sub-classes in an 
encapsulated way without knowing the concrete implementation of 
the other.

Like most languages C++ and D does not ensure sound object 
construction, but C++ is a bit better than D. When you allow 
super() to be called in arbitrary locations then modifications of 
ancestor classes are much more likely to cause issues for 
subclasses. So that approach does not scale.
