Nice!

Just one minor comment, instead of this long '--ad-hoc' line, you
should use a manifest file.

#+BEGIN_SRC shell
guix environment -C -N -E TERM guix --expose=/var/guix=/var/guix \
--ad-hoc emacs-no-x emacs-magit git git:send-email emacs-yasnippet
help2man pkg-config guile \
-- emacs --execute "(load-theme 'wombat)"
#+END_SRC

#+BEGIN_SRC shell
guix environment -C -N -E TERM guix --expose=/var/guix=/var/guix \
-m my-manifest.scm \
-- emacs --execute "(load-theme 'wombat)"
#+END_SRC

--8<---------------cut here---------------start------------->8---
(specifications->manifest
   '("emacs-no-x" "emacs-magit"
     "git" "git:send-email"
     "emacs-yasnippet"
     "help2man" "pkg-config guile"))
--8<---------------cut here---------------end--------------->8---

The main advantages are:
 - version control the file
 - reuse elsewhere, for example "guix install"
 - easy to locally extend:
   guix environment -m my-manifest --ad-hoc emacs-evil


Well, thank you for sharing and for the update.

All the best,
