I miss this in LISP. It might force me to better structure my programs so that a lot of this is dealt with in an up-front manner or simply can’t occur. I do it all the time in JS though and love it.

Your snippet is not working.

  #lang racket

  (define (division x y)
    (let/cc return
      (when (= y 0) (return null))
      (/ x y)))
