I'm pretty bad at naming and terminology, so…
#rustlang, how would you call a type that holds either a T or a &mut T and acts like the latter?
I don't think you will give a reasonable name to that concept in the abstract. I tend to name those types based on *why* I would have one or the other. (It's `RefMut` and not `&mut` in this case because it deals with RefCell but that's irrelevant)pic.twitter.com/s0vNuA59aK
