About C++, you should have a look at method name mangling, (google for
C++ mangling): there are different methods for different type of
arguments! You can consider the type of the hidden 'this' object in
the name mangling, so you don't need to prefix the method name by a
class name.


And mind:
          class a{void m(void);};
          class A{void m(void);};
!


Since you're interested in some generality, I'd advise you to study
Objective-C (also implemented originally as a pre-processor in front
of C), and CLOS (Common Lisp). With both, you will probably find out
that you have to broaden notably your preconceptions: OO models are
widely different from one language to the other, in general.
