And Guido says he won't break backwards compat again in Python 4 as he has learned the lesson. No tagged integers for life.

He learned the wrong lesson then. Which wasn't "don't break backwards compatibility", but:

1) If you break it, break it for compelling reasons.

2) If you provide a tool to convert, don't make it as awful as 2to3

Breaking language backwards-compatibility is one thing; breaking the extension API is less problematic, and breaking the extension ABI is better still.
