[racket] Why choose the 'let*' construct over the 'define' construct when both can have sequential scope?

[Don Green]

What is/are the reason(s) for choosing the 'let*' construct over the
'define' construct?

(define (print-two f)
  (let* ([_ (print (first f))]
         [f (rest f)]
         [_ (print (first f))]
         [f (rest f)])
    f))

(define print-two
  (lambda (f)
   (print (first f))
   (set! f (rest f))
   (print (first f))
   (set! f (rest f))
   f))

(void (print-two '(1 2))) ;=> 12
