First of all, thanks for your suggestions!

Right, packaging solves the problem because Guix takes care of patching
my script. But that comes at a significant cost in terms of deployment
complexity. It's certainly the right way to distribute black-box tools,
but my scripts are mainly illustrations for working with Guix. I want to
use them in a tutorial, saying "there is no built-in Guix functionality
for this, but you can write your own scripts interfacing with
Guix. Here's an example, download it, play with it, modify it to fit
your needs."

Not on my system. I am using Guix on top of Ubuntu, maybe for Guix
System it works out of the box. I'll try with a virtual machine.

Looking at those examples is certainly a good plan - I'll do and report
back!
