I wrote the below code

    def _matcher(seq, *args, **kwargs):
        for cls in seq:
            try:
                answer = getattr(maybe_promise(cls), method)(*args, **kwargs)
                if (answer is not None):
                    return answer
            except AttributeError:
                pass
    return _matcher
