Changing the repr() of a class?

I don't really understand what a metaclass buys you here.  I think I
might be missing something important, since Alex proposes it.

However, it appears that one could simply define the __repr__ method in
the regular class FunkyReprObject, ignore metaclasses altogether, and
wind up with the same results.  What is better about Alex' approach?

Yours, Lulu...
