[Python-Dev] Re: PEP 674 – Disallow using macros as l-value (version 2)

Hi, My PEP 674 proposed to change PyDescr_TYPE() and PyDescr_NAME() macros. This change breaks M2Crypto and mecab-python3 projects in code generated by SWIG. I tried two solutions to prevent SWIG accessing PyDescrObject members directly: https://bugs.python.org/issue46538 At the end, IMO it's too much work, whereas there is no need in the short term to modify the PyDescrObject structure, or structure inheriting from PyDescrObject. So I excluded PyDescr_TYPE() and PyDescr_NAME() macros from PEP 674 to leave them unchanged: https://python.github.io/peps/pep-0674/#pydescr-name-and-pydescr-type-are-le... Today, the PEP 674 only affects 9 projects on the top 5000 PyPI projects (+ 22 projects which have to re-run Cython). Victor
