Every time I've considered using super, I've eventually decided against it for reasons like this. I've always found a better way that doesn't introduce so may strange interactions between the classes involved.

I end up feeling the same way, for purely pragmatic reasons. However, cooperative multiple inheritance is a respected religion, and when practiced systematically can work well.

Also make a big distinction between super calls of init (which are a Pythonic wart and don't exist in other languages practicing multiple inheritance AFAIK) and super calls of regular methods (which are virtually problem-free as long as you agree on a base class that defines a method and derive from that class when you want to extend it).
