AFAIK there are two options. You can add a symbol after fn:
(let [fib (fn y [x] (cond (< x 2) x :else (+ (y (- x 2)) (y (- x 1)))))] (fib 5)) Or, as Bobby already suggested, you can use letfn: (letfn [(fib [x] (cond (< x 2) x :else (+ (fib (- x 2)) (fib (- x 1)))))] (fib 5)) -- You received this message because you are subscribed to the Google Groups "Clojure" group.
