def reuse(scope):
    """
    A decorator for transparent reuse of tensorflow
    `Variables <https://www.tensorflow.org/api_docs/python/tf/Variable>`_ in a
    function. The decorated function will automatically create variables the
    first time they are called and reuse them thereafter.

    .. note::

        This decorator is internally implemented by tensorflow's
        :func:`make_template` function. See `its doc
        <https://www.tensorflow.org/api_docs/python/tf/make_template>_`
        for requirements on the target function.

    :param scope: A string. The scope name passed to tensorflow
        `variable_scope()
        <https://www.tensorflow.org/api_docs/python/tf/variable_scope>`_.
