    Description:
        Given a list of booleans X and a list of booleans Y,
        determine whether each value in X is `True`, or
        whether its corresponding value in Y is `True`.

        >>> _or = Or()
        >>> _or([False, True, False], [True, True, False]).tolist()
        [True, True, False]
