You said that instance variables were just as bad as module globals. I was pointing out cases (w.r.t. software engineering, obviously, since that is what this thread is about) where module globals are worse.
Yes, programmers have to be aware of what they're doing, but that's true of any programming construct. It doesn't mean that we shouldn't identify the dangers.
