For the functions that take an other like this one, what do you think about using this wording:
Panics if the value in either
RefCellis currently borrowed.
This wording is taken from RefCell::swap

…s, r=frewsxcv RefCell: document panics in Clone, PartialEq, PartialOrd, Ord. This fixes rust-lang#47400 by adding: ```rust /// # Panics /// /// Panics if the value is currently mutably borrowed. ``` to said impls. They may panic since they call `.borrow()`.
