+Subject: [PATCH 2/2] Tests: update export_method tests for Python 3.10
+
+There is a change to how an error message appears for a static
+method in Python 3.10 (it now includes the original class name).
+This is not ideal, but for now we adjust the test rather than
+try to work out whether the code can be changed.
+
+This is something of an edge case.
