[plt-scheme] Using student-defined structures in a teachpack

I'd like to have a teachpack which allows the student to define her own 
Point struct such that the functions in the teachpack work with the 
student-defined Point. For example,


  (module a mzscheme
   (provide point->pair)

   (define (point->pair a-point)
    (cons (point-x a-point) (point-y a-point))))

Definitions window (with the above teachpack loaded):

  (define-struct point [x y])
  (point->pair (make-point 1 2))

Any tips on how such a teachpack could be written?
