+Subject: [PATCH] Use pre-3.10 serialization code on PyPy3.10
+
+The new serialization code for Python 3.10+ does not seem to work
+on PyPy3.10 7.3.13, as it causes:
+
+    ValueError: no signature found for builtin type <class 'code'>
+
+Switch back to the old code if PyPy is used, at least for the time
+being.  With this change, the test suite passes on PyPy3.10.
+
+Fixes #845
