Continuation with multiple values

Questions & Answers

Hello,

just an (expert) question , is there a way in call/cc to return multiple values?

i mean something like this but working:

> (call/cc (lambda (ct) (ct (values 1 2))))
. . result arity mismatch;
 expected number of values not received
  expected: 1
  received: 2
2

Leave off the values; just call the continuation with multiple arguments:

(let-values ([(a b) (call/cc (lambda (ct) (ct 1 2)))])
  (list a b))
3

cool.... :slightly_smiling_face:

works also with my def without changing the code but i did not knew it:

(def (foo) (return 1 2))

(foo)
