memfn predates anonymous function literals. I think it's better to use #(.charAt % i) than (memfn charAt i). Plus memfn won't let you add type hints on you arg so you can't avoid reflective calls. #(.charAt #^String % i) Christophe --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
