def __mul__(self, num):

        """ Duplicate itself and concatenate the results.

            It's basically a shortcut for `g().chain(*g().tee())`.

            Args:
                num: The number of times to duplicate.

            Example:

                >>> from ww import g
                >>> (g(range(3)) * 3).list()
                [0, 1, 2, 0, 1, 2, 0, 1, 2]
                >>> (2 * g(range(3))).list()
                [0, 1, 2, 0, 1, 2]
