Description
I recently came across this fun correctness bug in my code: https://github.com/rust-lang/rust/issues/65086.
I’m not sure how I could have known this without asking a compiler developer. Can we add a lint prohibiting RefCell borrows in funarg position since they prevent mutable borrows further down the stack?
