HAS-A to reuse modules? To start with you cannot have HAS-A on subprograms
in Ada.

So the claim is that reuse of generic units does not suffer the problems
reuse of inherited operations have? In particular, the discussion was about
conflicting names coming from independently developed modules. Are you
telling me that generics have less problems with name clashes? Seriously?
They have FAR worse problems with this!
