/// ### Explanation
///
/// It was expected that the marked code would emit a lint. This expectation
/// has not been fulfilled.
/// The `#[expect]` attribute can be used to create a lint expectation. The
/// expectation is fulfilled, if a `#[warn]` attribute at the same location
/// would result in a lint emission. If the expectation is unfulfilled,
/// because no lint was emitted, this lint will be emitted on the attribute.
///
/// The `expect` attribute can be removed if this is intended behavior otherwise
/// it should be investigated why the expected lint is no longer issued.
///
/// In rare cases, the expectation might be emitted at a different location than
/// shown in the shown code snippet. In most cases, the `#[expect]` attribute
/// works when added to the outer scope. A few lints can only be expected
/// on a crate level.
///
/// Part of RFC 2383. The progress is being tracked in [#54503]
