object.h contains an inline function that causes a -Wcast-qual warning from gcc. Since this file ends up visible in third-party code that includes Python.h, this makes it impossible to use -Wcast-qual in such code. The problem is the change c5cb077ab3c88394b7ac8ed4e746bd31b53e39f1, which replaced ob->ob_type by Py_TYPE(ob), which seems reasonable by itself, but Py_TYPE casts away the const, so it creates this problem. This is a regression in Python 3.10.
