Loading Common Lisp Libraries with GNU/Guix in a REPL

[jgart <jgart@dismail.de>]

Hi Guixers/Lispers,

What is the recommended way to load common lisp libraries that I install
with GNU/Guix on a foreign distro from a repl?

What are the common practices/workflows that the Guix community currently
uses with emacs-slime or sly to load common lisp libraries?

Is there a way of loading my dependencies with Guix the way they can be loaded 
automatically via quicklisp?

I've tried this so far:

```
$ guix shell sbcl sbcl-dexador rlwrap

$ rlwrap sbcl

CL-USER(1): (asdf:load-system :dexador)

`(asdf:load-system :dexador)` feels a bit verbose for loading a library
at a REPL.

Any help on best practices for common lisp workflows using GNU/Guix is
much appreciated.

all best,
