Brent Westbrook 3a32e56445 [syntax-errors] Unparenthesized assignment expressions in sets and indexes (#16404) ... ## Summary This PR detects unparenthesized assignment expressions used in set literals and comprehensions and in sequence indexes. The link to the release notes in https://github.com/astral-sh/ruff/issues/6591 just has this entry: > * Assignment expressions can now be used unparenthesized within set literals and set comprehensions, as well as in sequence indexes (but not slices). with no other information, so hopefully the test cases I came up with cover all of the changes. I also tested these out in the Python REPL and they actually worked in Python 3.9 too. I'm guessing this may be another case that was "formally made part of the language spec in Python 3.10, but usable -- and commonly used -- in Python >=3.9" as @AlexWaygood added to the body of #6591 for context managers. So we may want to change the version cutoff, but I've gone along with the release notes for now. ## Test Plan New inline parser tests and linter CLI tests.		2025-03-14 15:06:42 -04:00
