Consider these two modules:

--8<---------------cut here---------------start------------->8---
(define-module (a) #:use-module (b) #:export (from-a))
(define from-a 1)
--8<---------------cut here---------------end--------------->8---

and:

--8<---------------cut here---------------start------------->8---
(define-module (b) #:use-module ((a) #:select (from-a)) #:export (from-b))
(define from-b 2)
--8<---------------cut here---------------end--------------->8---

This fails:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,use(a)
While executing meta-command:
ERROR: no binding `from-a' in module (a)
--8<---------------cut here---------------end--------------->8---

whereas this succeeds (starting from a fresh Guile):

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,use(b)
scheme@(guile-user)> from-b
$1 = 2
--8<---------------cut here---------------end--------------->8---

Problem is that ‘define-module*’ processes exports after imports.

What about a patch along these lines:
