  (+ x 1))

(define (buz x)
  (let ((y x)

                   (lambda (n) (- n 1))

(define (fib n)
  (if (eq? n 0)
      n
      (+ n (fib (- n 1)))))

(for-each
 (lambda (x) (display x))

;; rest parameters

(define (baz one two . three)
  (pp three))

(baz "a" "b" "c" "d" "e" "f")

;; eval

(pp (eval-outlet '(baz 1 2 3 4)))

;; ->string

(display (->string '(foo 2 bar 4 "hel\nlo\"fdfsf")))

;; Example tracer using `alert`:

(require (trace "./trace"))
(trace.set-prompt alert)

(trace-source (let ((i (+ 4 5)))
                (+ i (* 2 (/ 3 4)))))
