/// The `unfulfilled_lint_expectations` lint detects lint trigger expectations
/// that have not been fulfilled.

/// ### Example
///
/// ```rust
/// #![feature(lint_reasons)]
///
/// #[expect(unused_variables)]
/// let x = 10;
/// println!("{}", x);
/// ```
///
/// {{produces}}
///
/// ### Explanation
///
/// It was expected that the marked code would emit a lint. This expectation
/// has not been fulfilled.
///
/// The `expect` attribute can be removed if this is intended behavior otherwise
/// it should be investigated why the expected lint is no longer issued.
///
/// Part of RFC 2383. The progress is being tracked in [#54503]
///
