One argument against the default is that it is specific to the str type. If you then tried to use join with an iterable of bytes objects and the default sep argument, you would get a TypeError. At least not having the default forces you to be explicit about which string type you're joining. -- http://mail.python.org/mailman/listinfo/python-list
