@larryhastings Hi, Larry. Would you mind to take a look? cc @vstinner

Before I look at the patch: what is the purpose of it? Argument Clinic is an internal tool for CPython, it can use the full API.

Yes. The Argument Clinic can use the full API. So this PR add an option to allow developer to use the limited C API or not.
What's the benefit of using the limited C API? It can hide the implementation details of the C API and more easy to extend.

More details in：
PEP 620: https://www.python.org/dev/peps/pep-0620/#relationship-with-the-limited-c-api
some victor's comment: https://bugs.python.org/issue41111#msg372307

This PR is stale because it has been open for 30 days with no activity.

After PEP 620 canceled, so I decide close this PR. I will reopen this PR when we continue update PEP 620, ref: python/peps#2923
Thanks Mike, Serhiy for your review.

@vstinner would of course know best, but my impression of the intent of withdrawing PEP 620 was that neither would it be re-opened and updated later or nor would the remaining changes be abandoned (as most of them were completed or mostly completed already), but rather they would be broken up into smaller separate PEPs.

@shihai1991, are you interested in reviving this effort?

Sure, of course. Sorry for my late replay ;)
