Hi,

The discussion on DeprecationWarning reminded me my old idea of a "development mode" for CPython: -X dev. Since Brett likes it, I post it on python-dev. Last year, I posted this idea to python-ideas but my idea was rejected: https://mail.python.org/pipermail/python-ideas/2016-March/039314.html In short: python3.7 -X dev script.py behaves as: PYTHONMALLOC=debug python3.7 -Wd -b -X faulthandler script.py

I would personally not add -b in those options. I think it was useful while porting stuff to 3.x, but not so much these days.

Regards

Antoine.
