Matthias Braun <matthiasb@fb.com> added the comment: This wasn't mentioned before: Having PyMemberDef part of the structmember.h is a big problem for users of PEP384/limited API, because structmember.h is not part of it. Which results in the odd situation that `Py_tp_members` or `PyDescr_NewMember()` are part of the limited API but technically you cannot use it because you are not supposed to include headers that are not part of `Python.h`. The proposed patch here, would fix this! ---------- nosy: +Matthias Braun _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue2897> _______________________________________
