define-values doesn't work with dot

[jcubic]

This works:

(call-with-values
  (lambda () (values 1 2))
  (lambda (x . rest)
     (display x)
     (newline)
     (display rest)
     (newline)))

But this does not:

(define-values (a . b)
  (values 1 2))
(cons a b)

The scheme code for define-values is taken from R7RS and works correctly in different implementations. So the problem my be in syntax-rules.

[jcubic]

This is issue with macros. This doesn't match. bar ... should match nothing.

(define-syntax foo
  (syntax-rules ()
    ((_ (foo bar ... . baz))
     '(foo baz))))

(print (foo (a . b)))
