Tracking Issue for #[loop_match]

[folkertdev]

The feature gate for the issue is #![feature(loop_match)].

This feature is based on rust-lang/rfcs#3720, though it does not exactly implement it. Rather, this is a language experiment to figure out how to impove that RFC. So, the RFC will eventually match the implementation we end up with, rather than the other way around.

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.
Discussion comments will get marked as off-topic or deleted.
Repeated discussions on the tracking issue may lead to the tracking issue getting locked.

Steps

• Implement the RFC

• Formatting for new syntax has been added to the Style Guide (nightly-style-procedure)
• Stabilization PR (see instructions on rustc-dev-guide)
