Aha!  I didn't think to check PLaneT.  Thanks.

 ;; with-temporary-file
 ;; creates a temporary file and automatically deletes it when finished
 (define-syntax with-temporary-file
   (syntax-rules ()
     [(_ file (args ...) e1 e2 ...)
      (let ([file (make-temporary-file args ...)])
         (lambda () e1 e2 ...)
         (lambda ()
           (when (file-exists? file)
             (delete-file file)))))]))

Looks awfully familiar :-)

Imagine this movie with Barbara Stanwyck and Fred MacMurray
and it would work for you.  Better still, just rent "Double
Indemnity" and the hell with it.
