/// The `const_err` lint detects an erroneous expression while doing
/// constant evaluation.

/// ### Example
///
/// ```rust,compile_fail
/// #![allow(unconditional_panic)]
/// const C: i32 = 1/0;
/// ```
///
/// {{produces}}
///
/// ### Explanation
///
/// This lint detects constants that fail to evaluate. Allowing the lint will accept the
/// constant declaration, but any use of this constant will still lead to a hard error. This is
/// a future incompatibility lint; the plan is to eventually entirely forbid even declaring
/// constants that cannot be evaluated. See [issue #71800] for more details.
