+Subject: [PATCH] mypy: get CI green for py39 (#9376)
+
+Due to Python 3.9's new parser, this has a different (and better) error
+message on Python 3.9.
+
+This is effectively a test of typed_ast / ast, so I don't think it
+matters too much. I'm happy to alternatively just get rid of the test
+altogether, or if people feel strongly, come up with a way to run the
+test when run with older Pythons.

+Subject: [PATCH] py39: fix mypyc complaint (#9552)
+
+I was trying to build wheels for Python 3.9 as part of #9536, but ran
+into this issue. You'll notice a couple hundred lines up msullivan
+points out that mypyc can't handle conditional method definition, so
+that's not an option here.
