This isn’t goofy, this is an extremely diffused “pattern” when you need to use non dynamic number sequences.

(defmacro gen-fib [size] (let [values (->> (iterate (fn [[a b]] [b (+ a b)]) [0 1]) (map first) (take size) (vec))] `(defn ~'fib [~'n] (~values ~'n)))) (macroexpand-1 '(gen-fib 10)) ;=> (clojure.core/defn fib [n] ([0 1 1 2 3 5 8 13 21 34] n)) (gen-fib 10) (fib 9) ;=> 34
