btw. This is precisely the reversion to a lower-level concern
that the founders of OOP sought to avoid.
But.. let's not go there.. ;-)
There is OOP done right, which is mainly done by Eiffel language,
which supports Multiple Inheritance without the Diamond of Death,
nor needing Interfaces.
All the rest add complexity with Interfaces and only support
single inheritance.
D falls into this group.
Bill Gates considered supporting Eiffel language as a Microsoft
language along with C# and VB.NET, but Eiffel's support of
Multiple Inheritance made function dispatching (which version of
this function should be called) take a little bit longer than a
standard vTable lookup. It was a constant time lookup, but took
a few more steps, thus slowing the program execution. The other
thing is that Eiffel compilation, even with "Melting Ice" and
modern workstations still takes significantly more time than
compiling C# for example.
There should be one rule which is: Whatever language or pattern
that you are using, the program should be "correct", that is,
obey the "business rules".
