Re: 04/07: guix: Add compression module.

[Ludovic Courtès]

Hi Mathieu,

That’s a long-overdue factorization, but…

guix-commits@gnu.org skribis:

> +(define-module (guix compression)
> +  #:use-module (guix gexp)
> +  #:use-module (guix ui)
> +  #:use-module ((gnu packages compression) #:hide (zip))

… a (guix …) module Should Not refer to a (gnu …) module¹.  When it
really has to, it should be via lazy-loading at run time, as is done in
(guix build-system …).

While I agree this should be factorize, I wonder if this should be
promoted to (guix compression).  The module name intuitively is a better
fit for the compression-related things currently in (guix utils).

Not sure, maybe (gnu compression) would make more sense?
