Seems reasonable. =) Do we feel the need to do a final "cargo check" crater run? (So we can cc the relevant people) |
|
OTOH if previous runs found no regressions, and we are deny by default, seems like overkill. |

Turn deprecation lint `legacy_imports` into a hard error Closes #38260 The lint was introduced in Dec 2016, then made deny-by-default in Jun 2017 when crater run found 0 regressions caused by it. This lint requires some not entirely trivial amount of import resolution logic that (surprisingly or not) interacts with `feature(use_extern_macros)` (#35896), so it would be desirable to remove it before stabilizing `use_extern_macros`. In particular, this PR fixes the failing example in #50725 (but not the whole issue, `use std::panic::{self}` still can cause other undesirable errors when `use_extern_macros` is enabled).
