In C and a couple other langages, int 0 is false, anything else is true. In Lisp (and IIRC), an empty list is false, anything else is true. I'm sure someone else could come with more than a couple other non-cryptic langages that just don't have a proper boolean type. Using "emptyness" as a false value in boolean expressions is not that uncommon, and it has proven so far to be a working solution. Also, returning the tested object instead of a bool just makes sens to me. FWIW, booleans are a late addition to Python, and quite a couple persons where worried that it would only lead to confusion. -- http://mail.python.org/mailman/listinfo/python-list
