Description:
 def _update_staticmethod(self, oldsm, newsm):
 """Update a staticmethod update."""

        # While we can't modify the staticmethod object itself (it has no
        # mutable attributes), we *can* extract the underlying function
        # (by calling __get__(), which returns it) and update it in-place.
        # We don't have the class available to pass to __get__() but any
        # object except None will do.
        self._update(None, None, oldsm.__get__(0), newsm.__get__(0))
