Yeah that's a whole nother can of worms for me with Rust, something that pisses me off a lot. By enforcing strict aliasing with no way to disable, Rust is making unsafe code intrinsically more unsafe, because you can't get predictable behavior. I'd rather it be called UB and work as intended anyways. But no, rustc devs in their infinite wisdom decided not to provide what is to me a core compiler flag. |

Personally I disagree. If you want to write freely aliasing code, I think it's better to use &UnsafeCell or &Cell or &RefCell, perhaps with an Arc (or my AliasPtr crate) instead of trying to convince rustc that &mut isn't exclusive.
