As a design choice, Rust prefers not to change the semantics of methods depending on the context, but instead to expose different methods. Arrays offer get_unchecked and get_unchecked_mut methods, which can only be called inside unsafe blocks. The one exception I'm aware of is that integer overflow panics in debug builds, and silently wraps in release builds. But in most other cases, there will be different separate methods with different semantics, requiring an unsafe context as appropriate.
