sets.Set class fail to hide its implementation. Subclassing it and overriding __init__ causes an exception during object creation.

Logged In: YES user_id=1326842 This is a bug in your code, you have to call the base class's __init__ method. The error does not occur during the object creation, but later when repr(obj) fails due to incorrect initialization.
