+Subject: [PATCH] Fix enum_type_object type on Python 3.11
+
+The enum_type_object type inherits from PyLong_Type which is not tracked
+by the GC. Instances doesn't have to be tracked by the GC: remove the
+Py_TPFLAGS_HAVE_GC flag.
+
+The Python C API documentation says:
+
+    "To create a container type, the tp_flags field of the type object
+    must include the Py_TPFLAGS_HAVE_GC and provide an implementation of
+    the tp_traverse handler."
+
+https://docs.python.org/dev/c-api/gcsupport.html
+
+The new exception was introduced in Python 3.11 by:
