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

    class desc(lazyval, ):
        def __get__(self, instance, owner):
            if (instance is None):
                return self
            try:
                return self._cache[instance]
            except KeyError:
                inst = ref(instance)
                @_weak_lru_cache(maxsize)
                @wraps(self._get)
                def wrapper(*args, **kwargs):
                    return self._get(inst(), *args, **kwargs)
                self._cache[instance] = wrapper
                return wrapper
        @_weak_lru_cache(maxsize)
        def __call__(self, *args, **kwargs):
            return self._get(*args, **kwargs)
    return desc

What's a good function header?
