Q3 2022 priorities

[StephanTLavavej]

In the third quarter of 2022, our priorities are:

• Implementing the C++23 features that have been accepted so far (more will be added during the July 25 plenary meeting)
  • Implementing P2465R3 Standard Library Modules (approved by LEWG, LWG, CWG, next step is plenary approval)
  • We also expect P2502R2 generator to be accepted soon, so we may look into implementing it
• Reviewing the PR backlog
  • We've made great progress here - from a peak of 80 PRs during Q1, to 55-70 during Q2, to ~30 right now 📉 😸
• Now that we've merged [benchmark] add gbenchmark #2780 adding Google Benchmark support and a first benchmark for std::copy[_n], we'll look into porting more benchmarks, e.g. from libcxx's test suite.

We could use some help with reporting and fixing libcxx test issues upstream - e.g. see the list of "likely bogus tests" with short explanations at:

(Once fixed upstream, we can update the STL repo's llvm-project submodule to pick up the fixes.)

If you have questions about our plans for this quarter, feel free to ask them here. (Note that compiler, IDE, etc. priorities are off-topic.)

[davidhunter22]

Thanks for the great update.

You mention the July 25 Plenary meeting. Is this the last meeting in which C++23 stuff can get voted in. If not what is the cut off?

[StephanTLavavej]

David Hunter (@davidhunter22) After the July plenary, C++23 will be feature complete and the "Committee Draft" ballot will begin. Then there will be 2 more meetings (a physical meeting in Kona, Hawaii in November, and another in early 2023) where CD ballot comments will be resolved (typically this involves a bunch of "patch papers" and CWG/LWG issues - in theory, no new features should be added during this time). and then C++23 will be effectively final. The official schedule is at P1000R4 and the July plenary is "2022.2 - tbd" there.
