It looks like this "through-cache" pattern was introduced some what recently: https://github.com/clojure/core.cache/blame/5b8474a532a7f12ca1a1fbbf8f82a6f816c16b29/src/main/clojure/clojure/core/cache.clj#L57 Since the readme references [these docs](https://clojure.github.io/core.cache/) which mention it I figured it'd be helpful to include.
