Install and load new emacs package without restarting it

["André A. Gomes" <andremegafone@gmail.com>]

Hi Guix,

I'm wondering whether it's possible to install an emacs package and
enable it without restarting emacs.

What I've tried:

- $ guix install emacs-nix-mode
- Locate /gnu/store/...emacs-nix-mode/share/emacs/site-lisp/nix-mode
- Run command dired-do-load from the directory above

Unfortunately it doesn't quite work.  It did load the package, but it
prints the following error when trying to enable the mode.

--8<---------------cut here---------------start------------->8---
execute-extended-command: Cannot open load file: No such file or directory, nix-mode
--8<---------------cut here---------------end--------------->8---

Thanks!
