// build-pass (FIXME(62277): could be check-pass?)

// rust-lang/rust#56327: Some occurrences of `dyn` within a macro are
// not instances of identifiers, and thus should *not* be caught by the
// keyword_ident lint.
//
// Otherwise, rustfix replaces the type `Box<dyn Drop>` with
// `Box<r#dyn Drop>`, which is injecting a bug rather than fixing
// anything.
