I quit around 2.2, never looked back. Python was a breakthrough scripting language ... in the 90s.
Also if you're fixing broken Python code, you're using Python, so no that doesn't really track.
What fundamental changes do you see since 2.2? If you're talking about the object model; objects in python were garbage before and after 2.2, and as a paradigm, it's mostly useless bureaucracy. Bleeding edge 90s ideas.
