Marko, I think the term binding makes sense in python due to how names work. In python and the following code: X = getit() Y = X X.changeit() In python, presuming getit() returns some form of object (so it has a changeit() member) then X and Y are bound to the same object, and changeit() will thus also affect the object that we see at Y. With a language with more ‘classical’ variable, the assignment of Y = X would normal make a copy of that object, so the value Y does not get changed by X.changeit(). -- https://mail.python.org/mailman/listinfo/python-list
