The following code:
(define-syntax define-lues
(syntax-rules ()
((_ () exp)
(call-with-values (lambda () exp) (lambda () 'unspecified)))
((_ (var . vars) exp)
(begin
(define var (call-with-values (lambda () exp) list))
(define-lues vars (apply values (cdr var)))
(define var (car var))))
((_ var exp)
(define var (call-with-values (lambda () exp) list)))))
(define-lues (a) (values (make-vector 3 9)))
(vector-length a)
In 2.0, either pasting this in the REPL or (load "...") a file
containing this produces the expected result, 3.
In the current master (f7582), pasting in the REPL produces the
same result, but loading from a file this produces the error:
> In procedure vector-ref: Wrong type argument in position 1 (expecting
> vector): (#(9 9 9))
I'm aware of the workarounds, I'm reporting the behavior itself.
