New to R5RS, do we reaffirm multiple values?
No. There is a better way.
Yes. In the absence of an alternative proposal that is as effectual as multiple values, I would argue for their continued existence.
I favor putting them in an optional module (which exports VALUES and CALL-WITH-VALUES), so that Thing One implementations do not *have* to support them, but if they do, will support them in a standard way.
I also support adding LET-VALUES and LET*-VALUES from SRFI 11, which make multiple values easier to use.
The WG voted to reaffirm multiple values as part of the core.
