[ty] Avoid duplicate syntax errors for await outside functions by ntBre · Pull Request #22826 · astral-sh/ruff (original) (raw)

Summary

This PR fixes astral-sh/ty#2598 by not emitting the YieldOutsideFunction syntax error for await expressions outside of functions. This isn't the most elegant fix, but as I noted in the TODO comment, I think a better long-term fix like not emitting YieldOutsideFunction errors for await at all would change the behavior of Ruff's stable F704 lint rule. We should be able to fix that and this TODO when resolving #19122.

Test Plan

We already had an existing mdtest for this behavior, so I just had to update it to remove the less specific error message
