That is your opinion. In the context of this discussion I don't see any problem to put C's union under "dynamic types". > The value of a union in C can be any of a > set of specified types.

When such a test is needed for the program with the union, it has it. -- Affijn, Ruud "Gewoon is een tijger." -- http://mail.python.org/mailman/listinfo/python-list
