[AccessD] Class costs & benefits

No no no no no, I interject. Multiple inheritance has been deemed
problematic in virtually language that offered it. It is simply too crazy a
construct for mere mortals such as myself to handle. For example, suppose
that I inherit from both class A and B, and each has a method of the same
name. How to distringuish which one you want? This path IMO leads to nuts
documentation and nuts programming. Even the C++ guys have abandoned this
approach.
