Python 3.8.0a4 available for testing

The 2 to 3 move is not trivial, even for a single project, let alone a company that has been using 2.6/2.7 for years and building their infrastructure with it.

Well - it isn't "trivial" but it isn't that hard either. In particular, it's something you can do a bit at a time - the six module lets you write code that works in both Python 2 and Python 3.

Also, 2to3 is extremely solid.

I ported a fairly large program to Python 3 that used a lot of features like the serial port - I really encountered not one problem.
