None of those under /gnu/store.  /gnu/store is explicitly read-only.
The actual source code you=E2=80=99d edit is a checkout of Guix.  See
<https://www.gnu.org/software/guix/manual/en/html_node/Building-from-Git.ht=
ml>.

In Scheme?  You could use =E2=80=98scandir=E2=80=99:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,use (ice-9 ftw)
scheme@(guile-user)> (scandir "/")
$2 =3D ("." ".." "bin" "boot" "data" "dev" "etc" "gnu" "home" "lost+found" =
"mnt" "proc" "root" "run" "sys" "tmp" "var")
--8<---------------cut here---------------end--------------->8---

and also =E2=80=98lstat=E2=80=99, etc., but that=E2=80=99s not quite a =E2=
=80=9Cshell=E2=80=9D.

HTH,
