Apologies for missing the reference to undefined functions in the above.
For present purposes, gx_shell can be simplified as follows:

#+begin_src example
  $> type gx_shell
  gx_shell is a function
  gx_shell ()
  {
      local preserve='.*GTK.*|.*XDG.*|.*DISPLAY.*|TERM|INSIDE_EMACS';
      guix shell --pure -CPWN -E "${preserve}" "${@}"
  }
#+end_src
