I think you need laziness to be a little more prevalent than that before it makes a difference. Haskell's super-concise Fibonacci sequence illustrates that:

  let fib = 1 : 1 : zipWith (+) fib (tail fib)

You may need to reevaluate what's possible in Clojure.

    (def fib (lazy-cat [1 1] (map + fib (rest fib))))

...Man, Clojure seems to have just about everything from every language ever.
