Desugaring control flow to letCC
View desugar-control.rkt
;; Control flow
;; basically, we provide a shadowed '^throw continuation, and then see what
;; we are handed. if it is an error (ie, an exception), we see if it matches
;; what we are catching, and if it doesn't, we re-throw. Since we are out of
;; scope of the current try/catch, we will now pick up whatever exception
;; continuation is outside. note that this obviously requires the entire program
;; to be wrapped in a try/catch that matches on everything (which it is).
