I have sent this email to two mailing lists for programming language proposals, the one for C++ and the one for Python. If you reply to this email, please make sure you reply to both. You can see the mailing list archives for this month for each list here:
C++ : https://lists.isocpp.org/std-proposals/2023/01/date.php Python : https://mail.python.org/archives/list/python-dev@python.org/2023/1/
Both C++ and Python have exception handling, however a C++ program which links with a Python library is unable to handle an exception thrown from Python.
Perhaps you should just use https://www.boost.org/doc/libs/1_81_0/libs/python/doc/html/index.html See also https://realpython.com/python-bindings-overview/ In both C++ and Python, exceptions can contain anything as their payload. The problem becomes a problem of mapping one language to the other, not just mapping exceptions. That makes it a general cross-language binding generation problem, so the forthcoming reflection/injection in C++ can certainly help, but just having a 'list' of exceptions isn't going to cut it either way.
