5 // the 2015 edition here is needed because edition 2018 changed the module system
6 // (see https://doc.rust-lang.org/edition-guide/rust-2018/path-changes.html) which means the lint
7 // no longer detects some of the cases starting with Rust 2018.
8 // FIXME: We should likely add another edition 2021 test case for this lint
