# Backlog Bonanza 2022-07-20

[GitHub query](https://github.com/rust-lang/rust/issues?q=is%3Aopen+label%3AC-tracking-issue+label%3AT-lang)

## What are we DOING?

* Take things that have been unstable for a while and "disposition them".
* Goal: Everything that is nightly only has one or more of the following labels, indicating the blocker(s) to stabilizing it:
    * S-tracking-ready-to-stabilize: Needs a stabilization PR (good to go :train:)
    * S-tracking-needs-to-bake: Needs time to bake (set a date? other criteria?)
    * S-tracking-impl-incomplete: Not code complete or blocking bugs
    * S-tracking-unimplemented: Implementation not begun
    * S-tracking-design-concerns: Blocking design concerns
        * This might be "doesn't quite seem to deliver value we hoped for" or "something doesn't feel right"
    * S-tracking-perma-unstable
        * Internal implementation detail of rustc, stdlib
    * S-tracking-needs-investigation
