I believe the concept had something to do with mutability or borrow checking. If I remember correctly it divided variables into 4(?) different categories depending on I think how (often) a variable could be changed? Each category had sort of a fancy name, something from programming language theory/design I assume. I know that’s not much info but I can’t track it down and it’s annoying me lol, anyone know it?
