Hi Ludo,

You closed this but the issue is still there, no? :-)

Because of this error:

--8<---------------cut here---------------start------------->8---
$ guix shell -C disarchive -- disarchive disassemble hello-2.12.1
Backtrace:
In ice-9/boot-9.scm:

[...]

ice-9/boot-9.scm:3329:6: In procedure resolve-interface:
no code for module (gcrypt hash)
--8<---------------cut here---------------end--------------->8---

solved by adding the package guile,

    $ guix shell -C disarchive guile -- disarchive disassemble hello-2.12.1

then, I think the contrary: having two packages is more convenient.

Well, from my point of view, two packages would be consistent with other
Guix packages as pandoc and ghc-pandoc for instance.  Plain name for the
CLI and <language>-name for the library in <language>, somehow.  The
<language> compiler/interpreter propagated/wrapped only with the CLI.

Somehow, I am proposing this attached patch.

Then tweaking around.
