If you have a personal Guix channel, any Guile code in it gets 
added to your load path.  I use this to include helpers which ease 
both system and home configurations, ex. this code for helping 
with offloading builds[1], or home services to launch 
jellyfin-mpv-shim[2] when I log in.

Perhaps the same setup would work for you, too.

Thanks,
