Why didn't you do it this way?

(let ((result 0))
  (loop for i from 0 to 3
    do (incf result i))
  result)

Why does it make worshippers of CL (COBOL-Like) so happy to do
everything inside of LOOP?

Why didn't you believe Paul Graham when he told you that LOOP
is a disaster?

Gauche Scheme:

(rlet1 result 0
  (dotimes (i 4) (inc! result i)))
