[issue10894] Making stdlib APIs private

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

My take on this:
- adding underscores to locally-defined private functions is good. +1
- -0.5 on "from warnings import warn as _warn"; it's useless complication, users should be able to realize warn() is a public API of the warnings module, not whichever else module using it
