I get: >>> class meta(type): pass ... >>> class cls(object): ... __metaclass__ = meta ... def __repr__(cls): ... return "I'm %s, an instance of %s" % (cls.__name__, type(cls)) ... >>> meta.__bases__ = (cls,)+meta.__bases__ >>> cls I'm cls, an instance of <class 'meta'> >>> assert type(cls) in cls.__subclasses__() >>> Of course, re-assigning meta.__bases__ comes too late to affect the construction sequence of cls.
