# 2022 Q2 P-high review

## Proposed Agenda

* Review the T-compiler P-high issues with no WG assigned, try to identify a WG to own them
* Review the issues with no team, make sure they have one
* Choose a category of remaining issues to review for rest of meeting
* e.g. A-linkage? A-LLVM? A-codegen? A-lifetimes?
