One way to do this is with `module->namespace' to get the namespace of
the module (I think that this is how `require/expose' works).  Another
way which is very convenient for testing is to use the sandbox:

  (require scheme/sandbox)
  (define e (make-module-evaluator (string->path "some-file")))

and at this point you have `e' bound to an evaluator that works inside
of your module, similarly to the repl in drscheme.
