I need to define syntax set!-values*, that will ignore _ in value place.
Such as
(define a #f)
(set!-values* (_ _ a) (values 1 2 3)) ; should set a to 3.
But I have two problems:
1. _ don't want to pattern match in syntax case. If I make it literal, I can't
match "anything else".
2. How to omit
5 matches
