Hey Michelangelo !

What is the reference you are mentionning ?

I saw Andy Wingo demonstrate something close to what you are looking
for at Guix Days 2020, but failed to reproduce it back home haha.

Maybe, if Andy see this thread and have some time to give some hints...
:)

I join snippets of what I have, but I don't know how to make them work
in the REPL...
