def __getitem__(self, item):
        """
        Retrieve the numpy RandomState instance associated with a particular
        stream.

        Parameters
        ----------
        item
            A variable of type RandomStateType, associated
            with this RandomStream.

        Returns
        -------
        numpy RandomState (or None, before initialize)

        Notes
        -----
        This is kept for compatibility with `tensor.randomstreams.RandomStreams`.
        The simpler syntax ``item.rng.get_value()`` is also valid.
