Am I wrong?
I think so. a = b will always make a a reference to (the same object as) b. What can be overloaded is attribute assignment: x.a = b can do anything from creating an attribute that references b to wiping your hard disk. I don't understand what you mean by "absence of aliasing", but conceptually every python variable is a -- well-behaved -- pointer. Peter -- http://mail.python.org/mailman/listinfo/python-list
