I've always been told that multiple inheritance is a bad thing, so I've tried to avoid. I didn't dig into why its a problem. I've recently come across a use of multiple inheritance in some python ...

I recently read an article entitled "Why is multiple inheritance so abhorred" in which code was reproduced without using code tags.
