Each call to create_fn will create a new instance (object) of the anonymous class for (fn [] (println "hi")) HTH, -- Laurent > > > Thanks for the help > -Patrick > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
