Replaces many use cases for dynamic setting of
_metaclass_----------------------------------------------------------------- For use cases that don't involve completely replacing the defined class, Python 2 code that dynamically set_metaclass_can now dynamically set_initclass_instead. For more advanced use cases, introduction of an explicit metaclass (possibly made available as a required base class) will still be necessary in order to support Python 3.
So, what are the use cases? I probably write metaclasses once a year, I wonder how much incentive there is to bring an additional complication to the already complicated class construction process.

Antoine.
