One other thing that the PEP doesn't make clear -- is it possible to combine '=' and ':=' to match a keyword argument with a sub pattern and capture the result? I.e. can you write
case Spam(foo = foo_value := Blarg()):
The full grammar in the Appendix makes this clear -- you can't write it like that, but you could write
case Spam(foo=(foo_value := Blarg()):
I'll get to your other points eventually.
