Hello Mathieu,

thanks for your helpful reply!

That looks really interesting, but I cannot meaningfully comment on the
bug report. Maybe it is time after the summer vacation season to poke
people more competent on the subject to comment :)

If by running you mean calling "guile the-above-file.scm", then I get
strange results. I just did a "guix system reconfigure"; "which guile"
returns "/run/current-system/profile/bin/guile". However then I get lots
of suspicious messages of this kind:
;;; In procedure load-thunk-from-memory: incompatible bytecode version
;;; WARNING: compilation of 
/run/current-system/profile/share/guile/site/3.0/guix/diagnostics.scm failed:
;;; Unbound variable: trivial-format-string?

How can byte codes be incompatible if on one hand they are part of the
profile, on the other hand I am running guile from the same profile?
