   (I would really like to be able to get line numbers
   so that the documentation that I autogenerate based
   on introspection can be ordered as it appears in the
   source. I poked at this a couple hours and failed.)

below is some code you can try.  to play: save as x.scm
and issue the shell command: guile -s x.scm.

(define (lc alist)
  (list (assq-ref alist 'line)
        (assq-ref alist 'column)))

(define (posn form)
  (display "posn: ")
  (write (cond ((not (pair? form)) "not a pair")
               ((source-properties form) => lc)
               (else #f)))
  (newline))

(define p (open-input-file "x.scm"))

(define (r)
  (read-enable 'positions)
  (let ((form (read p)))
    (or (eof-object? form)
        (begin
          (display "form: ")
          (write form)
          (newline)
          (posn form)
          (r)))))
