Hi, one could use lazymap: https://bitbucket.org/kotarak/lazymap. Unfortunately, it is broken at the moment. Have to bring up-to-date with 1.2 and later.
(defn person [name year-of-birth] (lazy-hash-map :name name :age (- 2011 year-of-birth))) The actual difference would only be calculated when the :age key is accessed. The result would then be cached. (It uses delays under the hood). Sincerely Meikel -- You received this message because you are subscribed to the Google Groups "Clojure" group.
