What if this was:

(module "hugo"
  (define a 1)
  (define* b 2))

That could also return a reference to the module, like your module*.

Have you considered using symbols instead of strings?

Can modules be nested?

What if...

(define (foo mod)
  mod.p)

(foo (module* "hugo"))
(foo (module* "walter"))
(foo 0)  ; this is an error, but where?

Oh, here's the difference between module and module*.
