The fact that the attributes of Python modules, like those of classes (and functions and instances) are externally mutable is a design feature, not a bug. (Call Python's dynamicity a design bug if you will, but that is different from a plain 'bug'.) This allows, for instance, programs to have an in-memory blackboard module with across-module variables that all other modules can write to as well as read. This design has been recommended several times on this list. We would, of course, all agree that having modules arbitrarily poking each others attributes is a bad idea. Indeed, that is the rationale for isolating all such pokes into a single blackboard module. Terry J. Reedy -- http://mail.python.org/mailman/listinfo/python-list
