I have no intention to use any part of Microsoft GitHub's Copilot.
And yet I have access and with a monthly frequency I receive the "Your GitHub Copilot access has been renewed" email.
Copilot is all over the UI and there's seemingly no way to fully disable it.
I managed to ask GitHub Support to disable it and they did, eventually.
Rust is experimenting with compile-time reflection in the form of type_info.
It's far from finished, but already advanced enough to implement a multi-array list type.
So I did just that.
