I think the "standard way" is to use call/cc (although I'm not an expert).
 Excuse my old version of scsh:

$ cat > test1.scsh
(define call/cc call-with-current-continuation)

(define (test1)
  (let loop0 ((x 1))
    (call/cc
      (lambda (k)
        (let loop1 ((y x))
          (if (= y 5)
              (k y)
            (loop1 (+ y 1))))))))
^D
$ scsh
