As I said before, C++ has a fundamentally different concept of what assignment means; it is of no use for understanding Python's assignment. Actually it is a big hindrance knowing about C++ assignment because it's difficult to explain to C++ users why Python can't and won't allow assignment to be overloaded. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
