I don’t fully grasp the details but I trust you.  :-)

Could you move the explanation as a comment in the code?

Grammar nitpicking: “allow NOUN to use bla”, like “allows us to use a
value.”  :-)

Thanks,

Thanks, this one-line change should be harmless :)

OK, I added some explanation to the code.

Thanks!  I didn't know this fact.

I've pushed this patchset, thanks for the comments!

Can some of you share their .emacs config file? I am especially
interested in the guix hacks. Do you pick up the load-path
dynamically? What packages are in your list?

Thanks,

Pj.

My ".emacs" can be found at <https://github.com/alezost/emacs-config>.
Not sure if it could be useful for anyone but me though.  I don't have
any particular guix hacks, except maybe that I install Emacs packages in
a separate guix profile.

I don't understand what you mean by "pick up the load-path dynamically".

I use about 60 emacs packages, but only 9 of them are managed by Guix;
for installing/upgrading the rest I use Quelpa¹ right now.  Eventually
I'll move to Guix completely to manage my emacs packages; I just have
not taken the time to add guix recipes for them.
