I'm still worried about hash of two unrelated objects returning the same value. Another implementation is to keep a hidden attribute of the object, and initialise it to the integer 0. Instead of using hash(key), you use the current value of the integer, then increment the integer by one. This is guaranteed to be unique, no matter what. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
