It seems to me that you deliberately misunderstood him. Why else would you type-cast the integers 2 and 1 to bools to supposedly demonstrate that there's nothing wrong with operations between bools returning ints? I mean, by that logic, it should be okay if we had False = [] True = [None] because: bool(False + True), bool(True + True) also gives (True, True). But that doesn't justify the choice of bools being lists any more than it justifies the choice of bools being ints. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
