@ericsnowcurrently Should we create the separate bpo issue if module changes are too noisy?

This is an extension module so let's avoid using _Py_ID(). I see the module defines Py_BUILD_CORE_MODULE, but ideally we wouldn't. So let's not expand the reliance on internal API.

PTAL

I try to remove the usage of Py_BUILD_CORE_BUILTIN, but things should be discussed before removing them.
So let's handle them as separate issues.

Yeah, something like that should be handled separately, after any relevant discussion. Note that not everyone may agree with me that stdlib extensions should not use internal API. It may be worth asking on python-dev.

LGTM

FYI, relevant bpo's:

As far as I can remember, there has not been any discussion on python-dev or Discourse (yet). I'm pretty sure Victor is interested in starting such a discussion. He's off CPython this week, but we can hear with him sometime next week.

BTW, this PR looks good to me :)

Thanks for the links!

Sounds good.
