+
+Wrap them with PY_VERSION_HEX for Python 3.11.

+Subject: [PATCH] libshiboken: Fix a crash in Shiboken::Object::isValid() for
+ Python 3.11
+
+The function is passed type objects for class methods, which caused
+it to crash.
+
+The first clause did not catch this, and so it was cast to SbkObject
+below.
+
+Add a type check to prevent this.

+Subject: libshiboken: Fix crashes with static strings in Python 3.11
+
+In Python 3.11, some strings come with a refcount above decimal
+1000000000, apparently indicating that they are interned. Replace the
+mechanism by PyUnicode_InternFromString().
