(memoize (fn [_#] (gensym "node")) How is that different than
(gensym "node") The latter returns a string, e.g., "node18051", the former returns a function that, when called, returns a string. Wrapping it in memoize just ensures that if you call it multiple times with the same argument, you get back the same string each time: (def f (memoize (fn [_#] (gensym "node")))) #'user/f user> (f 1) node18056 user> (f 1) node18056 user> (f 2) node18061 user> (f 2) node18061 user> (f 3) node18066 Sean -- You received this message because you are subscribed to the Google Groups "Clojure" group.
