We moved to Redis.io!

Why doesn't this command allow the 'withscores' option? Its incredibly useful on zrange, seems like the same usecases apply.

@sam: yes you are right, I'll add this option, adding it in the TODO list.

The codebase is so clean I was able to implement myself in a few minutes. forked and committed on github. I'm sending a pull request now.

I do not see this documented, but is count optional? For example, if the offset is 5 and the "count" is left off, then will all the items be returned from that offset?

no its not optional. Doesn't look like it would be hard to do but there may be a good reason why its not implemented.

Umm, why is there no ZREVRANGEBYSCORE?

+1 for ZREVRANGEBYSCORE

I hope we can get 'ZREVRANGEBYSCORE' implemented soon as it is very useful for retrieving a 'live list of items' in most recent order (when you use ticks as the score).

I'd love an option (or another call) to remove the members returned

Is there any easy way to sum first N elements or elements by range? Something like:

ZSUM key start end

At the moment to sum all scores we need to ZRANGE 0 -1 and then for each member call ZSCORE, not too efficient.

Is there other way to do that?

ZDIFF would be great - any thoughts?
