Functional programs have a different shape from imperative ones. The structure in a functional program comes entirely from the composition of arguments within expressions, and since arguments are indented, functional code will show more variation in indentation. Functional code looks fluid 1 on the page; imperative code looks solid and blockish, like Basic.

Example:

(defun bad-reverse (lst)

  (let* ((len (length lst))

         (ilimit (truncate (/ len 2))))

    (do ((i 0 (1+ i))

         (j (1- len) (1- j)))

        ((>= i ilimit))

      (rotatef (nth i lst) (nth j lst)))))

(defun good-reverse (lst)

  (labels ((rev (lst acc)

             (if (null lst)

                 acc

                 (rev (cdr lst) (cons (car lst) acc)))))

   (rev lst nil)))
