Yeah, those are really nice. It can be emulated pretty easily on
earlier pythons as well, but just having it as part of the standard
library is much better.

This is really cool! I had no idea it was possible to make a program
run on both 2.x and 3.x. Nice work! This makes it easy to merge these
patches today. Then, if we get buy-in about switching to Python 3, we
can drop 2.7 compatibility.

I've merged these three as they seemed fine. 2.2...yikes!

I also merged this one.

And this one. I have comments about a few and will continue reviewing
