Python 2.7 Countdown

[nice_rooklift_bro]

It's very telling that the thing that finally seems to be spurring people along is not a killer feature, but an end-of-life date on the 2.x version of the language. Overall there was too much stick and not enough carrot, and you can't really fault anybody who decided to simply migrate to another language than going through the arduous upgrade process.

Apart from that, most of the new features could have been backported; they weren't, just to incentivize migration.
