+// 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.
