Samuele would be the best one to answer this, but I'll give my opinion
anyway.  I think we should go with new-style classes when it turns out
to be easy, even when that puts us "ahead" of CPython, since
everything should ultimately be new-style.  I would guess that the
reason CPython classes might still be old-style in 2.4 is probably
internal/technical and not philosophical.

Samuele?
