Why can't I turn this Redis query result directly into a hash?

Question

This is confusing me to no end. Why am I unable to perform this operation directly on the query?

(rdb:1) $redis.zrange(key(p_id, range), 0, -1, {withscores: true})
["2008", "15769"]

(rdb:1) Hash["2008", "15769"]
{"2008"=>"15769"}

(rdb:1) Hash($redis.zrange(key(p_id, range), 0, -1, {withscores: true}))
NoMethodError Exception: undefined method `Hash' for Player:Module

(rdb:1) Hash[$redis.zrange(key(p_id, range), 0, -1, {withscores: true})]
{}

Answer 1

You should unpack the arguments:

Hash[*$redis.zrange(key(p_id, range), 0, -1, {withscores: true})]

Hash#[] takes also an array of pairs, so if the result is always a pair:

Hash[[$redis.zrange(key(p_id, range), 0, -1, {withscores: true})]]
