Thank you! I'm going to apply it. I have extracted the guile code and
put it to the "scheme side" of Emacs-Guix, also I have rewritten this
command a bit. The only thing: I don't like the name (neither
"guix-switch-profile" nor "guix-profile-apply"). I think
"guix-set-emacs-environment" suits better, as setting the environment is
exactly what this command does, WDYT?
You may look at my version of your patch (not in "master" yet) here:
https://notabug.org/alezost/emacs-guix/commit/a4bd696f0b8c564c1e654c426e9059cac1607996
Let me know, if you think something should be fixed there.
