I wrote the below code

    class C(object, ):
        x = property((lambda self: self._x))
        def __init__(self):
            self._x = 42
    c = C()
    c.__dict__['x'] = 43
    AreEqual(c.x, 42)
    class MyDescriptor(object, ):
        def __get__(self, *args):
            return 42
    class C(object, ):
        x = MyDescriptor()
    c = C()
    c.__dict__['x'] = 43
    AreEqual(c.x, 43)
    class MyDescriptor(object, ):
        def __get__(self, *args):
            return 42
        def __set__(self, *args):
            pass
    class C(object, ):
        x = MyDescriptor()
    c = C()
    c.__dict__['x'] = 43
    AreEqual(c.x, 42)

What's a good function header?

Here's a good function header?
