Then assoc/dissoc/etc. just delegates to the underlying map with the appropriate fiddling with the setter/getter. If you already have a map you can do something like: (require '[clojure.contrib.fnmap.PersistentMap :as fnmap]) (defn to-fnmap [the-map setter getter] (clojure.contrib.fnmap.PersistentFnMap. (assoc the-map ::fnmap/ setter setter ::fnamp/getter getter))) > That sounds a bit expensive. Did you try? "sounds" is not the best advisor. Sincerely Meikel
