        .. versionchanged:: 2.0
            Calling :meth:`stop` in this coroutine will stop the loop before the initial iteration is run.

        Parameters
        ------------
        coro: :ref:`coroutine <coroutine>`
            The coroutine to register before the loop runs.

        Raises
        -------
        TypeError
            The function was not a coroutine.
