commit 6f3c138dfa868b32d3288898923bbfa388f2fa5dAuthor: Serhiy Storchaka <storchaka@gmail.com>Date:   Wed Sep 6 23:55:42 2023 +0300    gh-108751: Add copy.replace() function (GH-108752)        It creates a modified copy of an object by calling the object's    __replace__() method.        It is a generalization of dataclasses.replace(), named tuple's _replace()    method and replace() methods in various classes, and supports all these    stdlib classes.
