Interpreter Dies Given Malformed Module Declaration

[Noah Lavine <noah.b.lavine@gmail.com>]

Hello all,

Running the following script with 'guile -l <filename>'

#!/usr/bin/guile
!#

(define-module (test-module)
  #:export should-be-a-list)

Gives this result:

;;; WARNING: compilation of load-test.scm failed:
;;; key wrong-type-arg, throw_args ("append" "Wrong type argument in
position ~A (expecting ~A): ~S" (1 "empty list" should-be-a-list)
(should-be-a-list))

ERROR: In procedure append:

Whereas I think a better result would be this:

Error compiling load-test.scm: expected list after #:export clause,
instead got 'should-be-a-list.

I'm not quite sure how to make this happen yet, so if anyone knows,
please let me know.
