did you check the FAQ?

people have done that before (why do you think it's
a FAQ?) -- usually people who haven't yet realized that
Python's standard type families are based on informal
interfaces, not subtypes.

(once you understand the difference, it's obvious that
we need more generic functions, not more methods ;-).
