	// ZAdd (accepts any value)
	n := zset.New()
	n.ZAdd(key, 1, "ced", nil)
	n.ZAdd(key, 1, "efg", &kv{1, 2})

	// ZScore
	_, score := n.ZScore(key, "ced")
	fmt.Println("score: ", int(score))
	// score: 1

	// ZRank
	rank := n.ZRank(key, "ced")
	fmt.Println("zrank: ", int(rank))
	// zrank: 0

	// ZRevRank
	rank = n.ZRevRank(key, "ced")
	fmt.Println("zrevrank: ", int(rank))
	// zrevrank: 1

	// ZIncrBy
	n.ZIncrBy(key, 300, "ced")
