Aaron Turon 5fe0bb743a Future-proof indexing on maps: remove IndexMut ... This commit removes the `IndexMut` impls on `HashMap` and `BTreeMap`, in order to future-proof the API against the eventual inclusion of an `IndexSet` trait. Ideally, we would eventually be able to support: ```rust map[owned_key] = val; map[borrowed_key].mutating_method(arguments); &mut map[borrowed_key]; ``` but to keep the design space as unconstrained as possible, we do not currently want to support `IndexMut`, in case some other strategy will eventually be needed. Code currently using mutating index notation can use `get_mut` instead. [breaking-change] Closes #23448		2015-03-20 10:46:31 -07:00
