I really like how it's done in Clojure, clean and simple:

(defn fib ^long [^long n]
  (if (<= n 1)
      1
      (+ (fib (dec n)) (fib (- n 2)))))
Compare to the Common Lisp code, where type hints are smeared all throughout the function:

(defun fib (n)
  (declare (optimize (speed 3) (safety 0))
           (fixnum n))
  (if (<= n 1)
      1
      (the fixnum (+ (fib (1- n)) (fib (- n 2))))))
