Feature or enhancement

Starting in Python 3.12, it is possible to receive vector calls in the limited API. However, it is not possible to issue them from a binary extension module compiled for the limited API.

Pitch

Since the PEP-590 is presumably stable at this point, I propose exposing more of it through the limited API. This would entail the functions

  • PyObject_Vectorcall
  • PyObject_VectorcallMethod
  • PyObject_VectorcallDict
  • PY_VECTORCALL_ARGUMENTS_OFFSET (a macro constant that is needed to use these effectively)

Previous discussion

Some related discussion took place here: https://discuss.python.org/t/ideas-for-forward-compatible-and-fast-extension-libraries-in-python-3-12. This PR Is specifically about item #5 from the list in the first post.

pythongh-98586: add whatsnew entry, related documentation fix
11b4bca 
PR python#98587 addressing issue python#98586 lacked a "what's new" entry.

While making those changes, I noticed an inconsistency in how
``PY_VECTORCALL_ARGUMENTS_OFFSET`` is declared in the underlying Sphinx
markup when compared to other macro constants like
``Py_TPFLAGS_HAVE_VECTORCALL``. This PR fixes that as well, which should
connect a few currently broken cross-references
