(define-module (there))
(define (f x) (* x x))

(define-module (here))
(define (f x) (+ x x))

(f 3) => 6

(define f-there
  (variable-ref (module-variable (resolve-module '(there)) 'f)))

(f-there 3) => 9
(f 3) => 6

this is not in any manual because the module system is slated for
redesign.  although it's been pointed out that implementation details
should not be made available, i still am wondering about the new
module system spec.  ie, will `module-variable' and `resolve-module'
still be around?
