Here's a good function header given the following:
I wrote the below code

    class foo:
        def func(self):
            return self
    class bar(object, foo, ):
        def barfunc(self):
            return foo.func(self)
    a = bar()
    AreEqual(a.barfunc(), a)

What's a good function header?
