[racket] macro for define-values?

I’m trying to code a macro that will define a variable number of identifiers. What I want is something like:

	(ref foo bar baz ...) 

and assign them an initial value of #<void>. The kludge I’ve come up with works, but there must be a better way to do this:

(define-syntax-rule (ref name ...)
  (define-values (name …) (values ((λ (name) (void)) #f) ...)))

>(ref foo bar baz)
>foo
#f

Thanks!
