And how do you convert a float to an int? __int__ is NOT going away; the sole purpose of __index__ is to enable sequence index functionality and similar use-cases for int-like objects that do not subclass from int. (For example, one might want to allow an enumeration type to index into a list.) -- Aahz (aahz at pythoncraft.com) <*> http://www.pythoncraft.com/ "19.
