/// ### Explanation
///
/// In the 1.77 release, the const evaluation machinery adopted some
/// stricter rules to reject expressions with values that could
/// end up holding mutable references to state stored in static memory
/// (which is inherently immutable).
///
/// This is a [future-incompatible] lint to ease the transition to an error.
/// See [issue #122153] for more details.
///
/// [issue #122153]: https://github.com/rust-lang/rust/issues/122153
