And yes, the error message could be clearer, although I'm not sure where that should be fixed.
How about in the Guix code that uses the semver stuff?
Guile doesn't know what packages correspond to what modules and it should probably stay that way.
It doesn't need to know, e.g. Guix could do
(define-module (whatever) #:autoload (bar) (foo))
(define (foo-if-available)
(catch 'unbound-variable
(lambda () foo)
(lambda _ #false)))
[...]
(define (stuff)
(define foo (foo-if-available))
(unless foo
(error "To use \"guix import crate\", you need to install
guile-semver"))
[... use foo ...]) Greetings, Maxime.
