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:

Let me know, if you think something should be fixed there.
