Common Lisp is too hard.

I still can't get my head around prefix notation. I heard Scheme is easier though. Seriously, why do practitioners of Lisp-like languages claim it's so good? I honestly cannot see the big deal, it's an old, slow, awkward and overall clunky language to use.

(loop for i from 1 to 100                                             
      do (cond ((= 0 (mod i 15)) (format t "FizzBuzz~%"))              
               ((= 0 (mod i 3))  (format t "Fizz "))                   
               ((= 0 (mod i 5))  (format t "Buzz "))                   
               (t                (format t "~a " i))))
