Why make things more obscure and complex when a simple check outside the library makes more sense?\r\n\r\nIn the only use case mentioned here, I'm pretty sure something like this communicates whatever is going on better:\r\n\r\n    foo = set.empty? ? [] : r.hmget(mapping_key, *set)\r\n\r\n\r\nBTW, not all of Ruby's APIs are well designed, so I wouldn't make that an argument ;-)","updated_at":"2011-10-11T17:56:07Z","url":"https://api.github.com/repos/ezmobius/redis-rb/issues/comments/2368904","id":2368904,"user":{"avatar_url":"https://secure.gravatar.com/avatar/ffd012d72e7f61639724878825ed25a3?d=https://a248.e.akamai.net/assets.github.com%2Fimages%2Fgravatars%2Fgravatar-140.png","url":"https://api.github.com/users/djanowski","id":2268,"login":"djanowski"}},"action":"created","issue":{"number":151,"created_at":"2011-10-04T16:50:20Z","pull_request":{"diff_url":"https://github.com/ezmobius/redis-rb/pull/151.diff","patch_url":"https://github.com/ezmobius/redis-rb/pull/151.patch","html_url":"https://github.com/ezmobius/redis-rb/pull/151"},"body":"","comments":7,"title":"Make MGET and HMGET work with no keys / fields","updated_at":"2011-10-11T17:56:07Z","url":"https://api.github.com/repos/ezmobius/redis-rb/issues/151","id":1815585,"assignee":null,"milestone":null,"closed_at":null,"user":{"avatar_url":"https://secure.gravatar.com/avatar/38d2521ec9092c9b8243b7a0bc9bbe50?d=https://a248.e.akamai.net/assets.github.com%2Fimages%2Fgravatars%2Fgravatar-140.png","url":"https://api.github.com/users/catwell","id":221332,"login":"catwell"},"html_url":"https://github.com/ezmobius/redis-rb/issues/151","labels":[],"state":"open"},"legacy":{"issue_id":1815585,"comment_id":2368904}}
