-   = note: reference of mutable static is a hard error from 2024 edition
-   = note: mutable statics can be written to by multiple threads: aliasing violations or data races will cause undefined behavior
-   = note: `#[warn(static_mut_ref)]` on by default
-help: mutable references are dangerous since if there's any other pointer or reference used for that static while the reference lives, that's UB; use `addr_of_mut!` instead to create a raw pointer
+   = note: this will be a hard error in the 2024 edition
+   = note: this mutable reference has lifetime `'static`, but if the static gets accessed (read or written) by any other means, or any other reference is created, then any further use of this mutable reference is Undefined Behavior
