What is this example supposed to accomplish?  Functions don't merely
not have a __self__ attribute set. The __self__ attribute has no
meaning on a function.

Let's take a different example.


class Dialog(Window):

    def __init__(self, parent, title, ok_callback):
        super().__init__(parent, title)
        self._ok_callback = ok_callback
        self._ok_button = Button(self, 'Ok')
        self._ok_button.bind(self._ok_callback)

def f(event):
    print("Hello world")

dialog = Dialog(None, "Example", f)
dialog.show()


Are you suggesting that dialog._ok_callback should be considered a
method of Dialog, despite the fact that the implementation of Dialog
and the implementation of f are entirely unrelated? If so, then I
think that most OOP practitioners would disagree with you.
