I'd be inclined to do this via simplegeneric. Let pprint do what it
currently does, but allow users to register implementations for
specific classes as they wish.
That is how pprint is implemented now. It register implementations for
specific classes and dispatch them by type (or rather by __repr__
implementation). But these functions have too complex and non-extensible
signatures and that is why this is an implementation detail.
There is an open issue for a pretty-printing protocol, but it is far
from any progress.
