That's the point where I dare to disagree. As I have pointed out in another posting in this thread, all other implementations have the same semantics for the basic behavior. I cannot see three different groups. Again, what's so surprising as the "natural" semantics described here: http://mail.python.org/pipermail/python-dev/2005-March/052041.html -- Christoph -- http://mail.python.org/mailman/listinfo/python-list
