// Under the 2015 edition with the keyword_idents lint, `dyn` is not
// entirely acceptable as an identifier. We currently do not attempt
// to detect or fix uses of `dyn` under a macro. Since we are testing
// this file via `rustfix`, we want the rustfix output to be
// compilable; so the macros here carefully use `dyn` "correctly."
