> (require kw-make-struct racket/match) > (struct foo (a b c) #:transparent) > (make/kw foo 'a 'b 'c) (foo 'a 'b 'c)
> (make/kw foo #:a 'a #:b 'b #:c 'c) (foo 'a 'b 'c)
> (make/kw foo #:a 'a 'b 'c) (foo 'a 'b 'c)
> (make/kw foo #:c 'c 'a #:b 'b) (foo 'a 'b 'c)
> (match (foo 'a 'b 'c) [(make/kw foo #:a a #:b b #:c c) (list a b c)]) '(a b c)
