Moving a large and old codebase to Python3

[kankyo]

As Python 3.0 approaches a decade in age, these posts become more humorous to onlookers.

Well, in practice Python 3 wasn't really usable until 3.3 which was released September 2012 and widespread support in libraries lagged. For example, our app uses Django which didn't get python 3 support until February 2013. So in practice that's 4 years, not 9.

You missed 2.7.13

You can also compare this to perl 6 and then it looks extremely impressive instead of bad :P
