behaviour difference when applying aspect to class vs instance

[chaoflow]

What to do about this?

https://github.com/chaoflow/metachao/blob/master/src/metachao/tests/test_intermethod.py#L31

        class C(object):
            def f(self):
                return 1

            def g(self):
                return self.f() * 2

        class a1(Aspect):
            def f(self):
                return 10

        c = C()

        self.assertEqual(a1(C)().f(), 10)
        self.assertEqual(a1(c).f(), 10)
        # BUT:
        self.assertEqual(a1(C)().g(), 20)
        self.assertEqual(a1(c).g(), 2)

g in the last line is bound to c, not a1(c), and therefore c.f is called instead of a1.f.
