I think that "avoiding code repetition" gets very much
to the bottom of what abstraction is about. I have always
thought of classes being for data abstraction, generic
functions being for procedural abstraction, and macros
being for control and syntactic abstraction.
I have found all of these kinds of abstraction to be useful.
They all have traps and pitfalls, too.
