New submission from STINNER Victor victor.stin...@haypocalc.com:
O? format was introduced by r4301 (15 years, 9 months ago).
PyArg_ParseTuple() was first documented in Python 2.2, but without the full
list of all formats. The format list was added to Python 2.3, but O? was
never documented. So I get that no third party progam use it.
In Python trunk, O? is no more used and so I propose to remove it to simplify
getarg.c (simplify getarg cannot be a bad thing). PyArg_ParseTuple() has now
better formats than O?.
--
O calls a callback: if the callback returns 0, raise an error; otherwise
gets the object. Example of callbacks: PyXXX_Check() function (eg.
PyInt_Check()).
--
The full Python test suite pass without any error on a patched Python (trunk).
