Hmm, this is odd; I'm not sure how the `uniqueKeys` was ever actually being enforced here. What you have will better enforced the `uniqueKeys` contraint, but I'll check with the original author first just to make sure.

Also, it seems that the `uniqueKeys` contraint could lead to a better performing cache since a map from key to item could also be maintained.
