示例
Pass base classes inside six.with_metaclass(Meta, *bases) rather than in the class definition base list where they are silently discarded, and avoid add_metaclass which bypasses __prepare__ and breaks zero-argument super in Python 3

契约
- six.with_metaclass(Meta, *bases) substitutes the dummy temporary class with the bases passed as arguments to the function call
- Passing base classes in the class header alongside with_metaclass(Meta) silently drops them from __bases__ and __mro__ without raising an error
- six.with_metaclass properly executes Meta.__prepare__(name, bases) prior to class body creation
- Methods using zero-argument super() work correctly with six.with_metaclass
- six.add_metaclass bypasses Meta.__prepare__ and breaks Python 3 zero-argument super() due to stale __class__ closure cell binding
