+    SORT list LIMIT 0 2 ASC
+    vals, err := client.Sort("list", redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
+
+    ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2

+        Max: "+inf",
+        Offset: 0,
+        Count: 2,
+    }).Result()
+
+    ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
+    vals, err := client.ZInterStore("out", redis.ZStore{Weights: []int64{2, 3}}, "zset1", "zset2").Result()
+
+    EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
