Sorry, something went wrong.
Also moved an auto variable that got consted into its innermost necessary scope.

Please do not add const to PyObject pointers (and PyTypeObject is a subtype of PyObject). They are inherently mutable. If the particular function does not mutate them in the particular Python version, it is just an implementation detail.

Will do. I know we've discussed before, but this was an old branch. Sorry. I'll resubmit.

Note that this is the same type of patch as #19185, but in a different source file. If it's easier for the folks that go through these patches to have similar changes to multiple source files put together in one PR, let me know and I'll do that going forward.
