For example, PyObject is much better to implement using C++ class, it will bring RAII that will reduce number of issues not free memory in CPython
Well, yes, that's the C++ Kool-Aid we're all supposed to drink. But it has its costs, too. How does it affect performance? How does it interact with slots, __new__, metaclasses, and other features of the Python class hierarchy, especially when coded as C? What about translating all of the accelerated modules written in C using the existing stable ABI? Have you looked at how this would affect NumPy, Pandas, and cffi? That's just a bunch of random related software, there are plenty of others (not to mention non-public software that neither of us has access to that may be affected). Really, you need to bring new information specific to Python rather than this generic "C++ is great" advocacy.

No thanks, if it's not text I'm not going to look at it. I don't have time to watch videos with no explanation, and best guess is 90% of it I already know, just as I don't think you've yet written anything I didn't already know.
Without RAII - introduced the most dangerous errors !!
List the CVEs. I'll happily go read those! Steve
