Subject: Re: [racket-users] multiple-value version of in-value
My package `adjutor` has a few variants of this, like `in-value*`:
https://docs.racket-lang.org/adjutor/Stable.html#(part._.Sequence_.Constructors)
They can all be used as first-class procedures, but that does involve a little

Very nice. I have installed the package. Thanks very much,
Jos

Recently I needed a multiple value version of in-value.
Does something like that exist already?
I could not find it, so I made one:
(define-syntax (in-values stx)
(syntax-case stx ()
((_ expr)
#'(make-do-sequence
(λ ()
(values
(λ (p) expr)
(λ (p) #f)
#t
(λ (p)
