1 | // This is just like unreachable_pub.rs, but without the |
2 | // `crate_visibility_modifier` feature (so that we can test the suggestions to | |
3 | // use `pub(crate)` that are given when that feature is off, as opposed to the | |
4 | // suggestions to use `crate` given when it is on). When that feature becomes | |
5 | // stable, this test can be deleted. | |
