Note that the open() function is special in this respect -- I don't see you doing the same to range() or hash(). If this is deemed a useful feature (for open()), we can make a rule about which built-ins you cannot override like this and which ones you can. --Guido van Rossum (home page: http://www.python.org/~guido/)
