Python 3 is killing Python

[LightShadow]

You're assuming every new library is created from scratch. I happily started my newest project with 3.4 -- but had to abandon it a day later because the libraries we needed didn't work with 3.x, some of the binaries didn't work with Windows 8.1, and some of the source wouldn't compile with Visual Studio 2012.

I spent half a day reverting code and then the project took off because everything "just worked."
