  ;; Requires a module and exposes some of its unprovided
  ;; (non-syntax!)  identifiers.
  ;; USAGE: (require/expose MODULE-NAME (IDS ...))
  ;;   where MODULE-NAME is as in the MzScheme manual (i.e.,
  ;;   a standard module spec) and IDS are the un-provided
  ;;   identifiers that you wish to expose in the current
  ;;   module.
  ;; Based on a macro by Raymond Racine
