// This checks the behavior of how nested macro_rules definitions are handled
// with regards to edition spans. Prior to https://github.com/rust-lang/rust/pull/133274,
// the compiler would compile the inner macro with the edition of the local crate.
// Afterwards, it uses the edition where the macro was *defined*.
//
// Unfortunately macro_rules compiler discards the edition of any *input* that
// was used to generate the macro. This is possibly not the behavior that we
// want. If we want to keep with the philosophy that code should follow the
// edition rules of the crate where it is written, then presumably we would
// want the input tokens to retain the edition of where they were written.
//
// See https://github.com/rust-lang/rust/issues/135669 for more.
//
// This has two revisions, one where local=2021 and the dep=2024. The other
// revision is vice-versa.
