-Subject: [PATCH] python: enum: fix build for Python 3.11
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Python 3.9 introduced Py_SET_SIZE function to set size instead of
-relying on Py_SIZE() as a macro [3.9].
-
-Python 3.10 started to encourage to use Py_SET_SIZE instead of
-assigning into return value of Py_SIZE [3.10].
-
-Python 3.11 flips the switch, turn Py_SIZE into a function [3.11],
-thus Py_SIZE(obj) will be a rvalue. We need to use Py_SET_SIZE
-to set size now.
