I did say "runtime borrow checking" ie using them together. Example: `Rc::new(RefCell::new(value));`. This will panic at runtime. Maybe I should have used the phrase "dynamic borrowing" ?

You don't need different threads. I said concurrency not multi-threading. Interleaving tasks within the same thread (in an event loop for example) can cause panics.
I understand what you meant (but note that allocating an Rc isn’t necessary; &RefCell would work just fine). I just didn’t see the “subtle linguistic distinctions” - and still don’t… maybe you could point them out for me?

Yeah, it is a crappy example. Ignore me. I just re-read and the rustdoc has no “subtle linguistic distinctions”.
