This is a tracking issue for the change to not special case the type of diverging blocks.

About tracking issues

Tracking issues are used to record the overall progress of implementation. They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions. A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature. Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.

  • Edition 2024: don't special-case diverging blocks as much #123590

  • Add a list against control-flow keywords used with ; at the end of a block (e.g. { return; }).
  • Add a FCW for special cased blocks #125793

• Plan regarding the special-casing of diverging blocks #125936 (comment)

This isn't going to happen for Rust 2024, and there's no current plan otherwise to change the status quo, so let's remove this from the edition and close the tracking issue.
