LISP, why bother with parentheses?


Mostly because it's fun, and it will make recursion your best friend!

I just started learning R5RS Scheme and it's kind of awesome, I started noticing all the little things in my program, started using recursion and made a little pow function -.-


(define  loopow
  (lambda (count x n xpow)
    (if (< count (- n 1) )
     (loopow (+ count 1) x n (* x xpow))
     (abs xpow))
     )
   )
(define (pow x n) (loopow 0 x n x))


Having to call the function from another function was a shock for me, I'm not used for it in C, but the complete product is pretty awesome and I'm proud of myself being able to write it.

Recursion FTW!
