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.
