IMHO the core of the PEP 565 is to propose a compromise to separate
"own code" and "external code" (cannot be modified).

I'm unhappy with this suboptimal compromise: "only __main__ is my own
code". Maybe we need something to declare the code that we own, to
enable warnings on them. Just a simple helper on top of
warnings.filterwarnings()? Or maybe I'm already in the "the better is
the enemy of the good" greay area :-)
