STINNER Victor <vstinner@python.org> added the comment:

Note that structmember.h pollutes global namespace with macros that do not have conventional Py_ or PY_ prefix. READONLY and RESTRICTED macros seem to be most likely to conflict with other code.

One small enhance would be to add such prefix when Py_LIMITED_API is defined. ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue2897> _______________________________________
