Arrgh, good catch.

This is getting annoying.  I will instead push something along these
lines shortly:

That will allow us to have circular dependencies among modules.

This is because Guile supports this:

  (define-module (a) #:use-module (b) #:export (foo))
  (define (foo) (bar))

and

  (define-module (b) #:use-module (a) #:export (bar))
  (define (bar) (foo))

... but not if ‘foo’ or ‘bar’ were directly referring to each other at
the top level, as in (define foo bar).

Thanks,
