[plt-scheme] Problem with defmacro and modules

Hi!

I stumbled across strange behaviour using mzscheme 360; the following
code will fail with "reference to undefined identifier: module":

;;-----------------------------------------------------------------
(module baz (lib "r5rs.ss" "r5rs"))

(module foo mzscheme
  (require baz)
  (provide expand-foo)
  (define (expand-foo form)
    'foo-expansion))
  
(module bar mzscheme
  (require (lib "defmacro.ss"))
  (require-for-syntax foo)
  (provide bar)
  (define-macro (bar . forms) (expand-foo (cons 'bar forms))))

(module qux mzscheme
  (require bar))
;;------------------------------------------------------------------

I guess this is a bug in defmacro and/or the module system. Any ideas?

Thanks, Rotty
