Here's a good function header given the following:
I wrote the below code

    def wrapper(func):
        @wraps(func)
        def wrapped_func(request, *args, **kwargs):
            if (not settings.RATE_LIMITING):
                return func(request, *args, **kwargs)
            if client_is_exempt_from_rate_limiting(request):
                return func(request, *args, **kwargs)
            try:
                user = request.user
            except Exception:
                user = None
            if (not user):
                logging.error(('Requested    rate-limiting    on    %s    but    user    is    not    authenticated!' % func.__name__))
                return func(request, *args, **kwargs)
            rate_limit_user(request, user, domain)
            return func(request, *args, **kwargs)
        return wrapped_func
    return wrapper

What's a good function header?
