[issue8733] list type and UserList do not call super in __init__ and therefore, they cannot be parents in a multiple inheritence scheme

[Raymond Hettinger]

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:

There will always be classes that don't call super() init, sometimes for efficiency and sometimes to preserve their internal invariants.

Also, __init__() isn't the only method affected.  For a perfectly cooperative class, all of the methods would need to call super().

See how to handle this in the "How to Incorporate a Non-cooperative Class" section of: https://rhettinger.wordpress.com/2011/05/26/super-considered-super/
