In CPS, n-return values just means your continuation is n-ary. You don't need to allocate cells to put all your return values in. I don't know if Racket's implementation doesn't need to allocate, but that's also a bonus. -Ian ----- Original Message ----- From: "David Van Horn" <dvanh...@ccs.neu.edu> To: users@racket-lang.org Sent: Wednesday, December 14, 2011 7:56:15 AM GMT -05:00 US/Canada Eastern Subject: Re: [racket] Multiple return values

In what > situations is it useful? It's useful in situations where several values are the result of a single computation. A simple example of this situation is the quotient and remainder of an integer division. There's also a more philosophical argument for them which is that, for symmetry, functions should be able to produce multiple results since they may consume multiple inputs.
