Python 2 EOL is only a few days away[*]. We made configure bitch about it in commit e5abf59eae "Deprecate Python 2 support", 2019-07-01. Any objections to retiring it now, i.e. in 5.0?

Cc'ing everyone who appears to be maintaining something that looks like a Python script.

Thanks for the reminder!

I'll be honest: even if somebody in this list objects to dropping Python 2 support, I'm not willing to be maintainer of a Python 2 codebase in 2020. The only reason for not doing it in 4.1 was the tests/vm/netbsd breakage we took very long to debug and fix.

I have just submitted this pull request:

I am pretty sure that I am not a python maintaainer at all.

But anyways, python3 is only at python3.7.
python3.0 debuted at 2008, so ...

And anything else that you can think that endorses the change.

Later, Juan.

I wasn't exactly "willing" in 2019...

Perhaps we can formulate a new law that says:

"Any person who says that he/she is pretty sure he/she is not a maintainer of something at all, is, in fact, and for sure, the maintainer of that thing."
