Defining a global var just for local binding is not very clean, and unnecessary; (defn f [] (with-local-vars [myvar 1] (var-set myvar 2) (var-get myvar))) (f) -> 2 Check out the documentation for with-local-vars for an explanation. -- Jarkko --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
