I think opening a thread in https://discuss.python.org/c/users to talk about deciding between the usage of functions and macros (discussing when each may be appropriate) would be beneficial to the community at large.

Apologies if I added to that, I certainly respect your judgement on this issue. Pretty much everyone involved in this discussion has more experience in working with the CPython C-API than I do, you most of all (as far I'm aware). My perspective was coming from someone attempting to understand it better, and explaining how those learning the C-API might find it confusing.

I don't find the code itself to be at all "evil", just potentially confusing. That long-stable code has provided a lot of benefit over the years, and I can definitely appreciate the effort that was put into writing it.
