Feature or enhancement

Has this already been discussed elsewhere?

I have already discussed this feature proposal on Discourse

Links to previous discussion of this feature:

• [C API] Convert a few stdlib extensions to the limited C API (PEP 384) #85283
• gh-85283: Extending Argument Clinic to support to use the limited C API. #26080

Proposal:

I propose adding support for the limited C API to Argument Clinic. Since Argument Clinic supports a wide diversity of parameter types and object types, I propose to add the support incrementally (step by step).

The final goal is to restrict some stdlib C extensions to the limited C API.
