Now we can lint for the expressions like _&_>>_, _<<_^_, etc. And will suggest to add parentheses like _&(_>>_) and (_<<_)^_.
I get implementation suggestions from #8735 (review).

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @Jarcho (or someone else) some time within the next two weeks.

Please see the contribution instructions for more information. Namely, in order to ensure the minimum review times lag, PR authors and assigned reviewers should ensure that the review label (S-waiting-on-review and S-waiting-on-author) stays updated, invoking these commands when appropriate:

  • @rustbot author: the review is finished, PR author should check the comments and take action accordingly
  • @rustbot review: the author is ready for a review, this PR will be queued again in the reviewer's queue

@rustbot rustbot added the S-waiting-on-review Status: Awaiting review from the assignee but also interested parties label Nov 28, 2024
