As for True and False, bool has to be able to return them, because the whole purpose of exposing bool is so people can call it: if bool(some_value) was an error, that would defeat the purpose of having bool!
Bool is different, because it doubles as a function for coercing things to bool. There's no corresponding concept of coercing something to None, or Ellipsis, etc. -- Greg -- http://mail.python.org/mailman/listinfo/python-list
