What about using protocols for this job?
(defprotocol ConvertibleToClojure
(->clj [o]))
(extend-protocol ConvertibleToClojure
java.util.Map
(->clj [o] (let [entries (.entrySet o)]
(reduce (fn [m [^String k v]]
(assoc m (keyword k) (->clj v)))
{} entries)))
java.util.List
(->clj [o] (vec (map ->clj o)))
java.lang.Object
(->clj [o] o)
nil
(->clj [_] nil))
(defn as-clj-map
[m]
(->clj m))
Let me know if this works for you & meets your performance requirements.
