Hi Ludo,

This is really great! I’m very happy that this is finally in the master
branch. Thank you!
As discussed on IRC, there is a problem when running “guix pull” with an
older version of Guix that is still using Guile 2.0, which seems to be
adequately fixed by your patch:

A remaining problem for me was that “(guix docker)” could not be built
because “(json)” was supposedly not available.
None of this seems to be a problem when using Guile 2.2.

I think we should do this anyway and try to split up large modules and
reduce inter-module dependencies.

Exciting!
