"of_type" doesn't really work for me - why not just name it "metaclass"?
def metaclass(meta):
class MetaclassMixin(object):
__metaclass__ = metaclass
return MetaclassMixin
class MyClass(metaclass(SomeMetaclass)):
pass
Off the top of my head, I can't see any reason this wouldn't work in the
case of multiple compatible metaclasses (due to inheritance).
