I've been pondering this one too. The only downside I can think of is
that code that inherits from class int to add some method (e.g. a
class hexint whose repr() and str() call hex() instead) will no longer
inherit any implementation, and thus won't be very useful. Inheriting
from short or long doesn't quite solve the problem either.
