I believe : is the convention the redis community uses to namespace keys.
From my experiments, this module supports passing in an array as keys which will automatically be joined... but with a comma instead ,
Why is this? Is it because keys were joined with .join without specifying the character?
Has there been a discussion or an issue raised as to why , was picked? accidental or not?
And is there any chance of this being changed? (fixed?) Maybe in a 0.9.0, so as not to break existing users? Or maybe make it configurable via the createClient options hash?
Ah, this seems to be a byproduct of toString()-ing an array.
Saw this used in https://github.com/tblobaum/redis-graph/blob/master/index.js#L153
I guess I should turns this into a feature request :/
