We just had our next weekly meeting. You can find the notes in this section of the DropBox paper document, but I’ll extract out some of the highlights here:
Summary of the last week
First of all, let me just say: Go Team! We closed out most of the issues I opened last week and made some real progress on NLL performance (here is a graph showing clap-rs-check results over the last week). There are still a few PRs pending, as well.
Thanks to:
You all are great! 
This week
This week we are turning our focus to ICEs and major diagnostic issues. If you’d like to participate, you can search through the Rust 2018 Preview 2 milestone for the full list of issues, but here is a selection that I called out for this week as “really good to get done”. They all have at least some mentoring instructions:
-
#46908 — implement
-Zborrowck=migratemode. Pretty high priority. - ICEs: #50467, #51345, #51351
- Performance tweaks: #52027
- Diagnostic tweaks: #51167
In addition, I expect to be opening some new issues during the week:
- First, we have started a crater run, and when it comes back we are going to need help going through the results.
- Second, we will be opening various issues relating to lifetime error diagnostics, but that is blocked on some foundational work landing in master.
