I think many people find this ugly. I have a little helper function
that
I use to make things a little clearer (at least in my eyes). Of course,
these things are always in the eye of the beholder (as evidenced by the
original message).
def of_type(metaclass):
class MetaclassMixin(object):
__metaclass__ = metaclass
return MetaclassMixin
... and then I simply use this on my classes when I define them:
class MyClass(of_type(SomeMetaclass)):
...
I find this to be fairly useful, and simple.
