+Subject: [PATCH 1/2] Update classmethod expectations (again) for Python 3.11
+
+It seems that the classmethod behavior in Python 3.11.0b1 is back
+to the one found in Python 3.8.  Adjust the test expectations again.
+This time around, we expect the "old-new" behavior in CPython 3.9
+and 3.10 only.
