### [Approved RFCs](https://github.com/rust-lang/rfcs/commits/master)
Changes to Rust follow the Rust [RFC (request for comments) process](https://github.com/rust-lang/rfcs#rust-rfcs). These
are the RFCs that were approved for implementation this week:
* *No RFCs were approved this week.*
### Final Comment Period
Every week, [the team](https://www.rust-lang.org/team.html) announces the 'final comment period' for RFCs and key PRs
which are reaching a decision. Express your opinions now.
#### [RFCs](https://github.com/rust-lang/rfcs/labels/final-comment-period)
* *No RFCs entered Final Comment Period this week.*
#### [Tracking Issues & PRs](https://github.com/rust-lang/rust/issues?q=is%3Aopen+label%3Afinal-comment-period+sort%3Aupdated-desc)
* [disposition: merge] [Evaluate place expression in `PlaceMention`](https://github.com/rust-lang/rust/pull/104844)
### [New and Updated RFCs](https://github.com/rust-lang/rfcs/pulls)
* [new] [Casting From by as_cast](https://github.com/rust-lang/rfcs/pull/3413)
* [new] [Proposal: add range value type and range value conversions between different ranges.](https://github.com/rust-lang/rfcs/pull/3412)
* [new] [Explicit move binding mode](https://github.com/rust-lang/rfcs/pull/3410)
* [new] [Guaranteed TCO (tail call optimization)](https://github.com/rust-lang/rfcs/pull/3407)
### [Call for Testing](https://github.com/rust-lang/rfcs/issues?q=label%3Acall-for-testing)
An important step for RFC implementation is for people to experiment with the
implementation and give feedback, especially before stabilization. The following
RFCs would benefit from user testing before moving forward:
* *No RFCs issued a call for testing this week.*
If you are a feature implementer and would like your RFC to appear on the above list, add the new `call-for-testing`
label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature
need testing.
