Beautiful engineering

Wow. Sometimes I witness some engineering that leaves me feeling joy and inspiration. I felt that way about the Golden Gate Bridge. But sometimes I feel that way about code. For instance, right now, I just learned that the defun macro for Clojure allows this function for calculating a fibonacci number.

A fibonacci function:

(defun fib
    ([0] 0)
    ([1] 1)
    ([n] (+ (fib (- n 1)) (fib (- n 2)))))


(fib 10)
;; 55

That is one of the most beautiful things I’ve ever seen.
