Part of the issue with 3 is that the changes were so minor that they were just annoying. Like 2/3 now equals 0.66 instead of 0, thanks for the hard-to-find bugs. `print "foo"` no longer works, cause they felt like it. Improvements like str being unicode made more sense but were quite disruptive and could've been avoided too, just add a new type.

What I would've preferred is they leave all that stuff alone, add nice features like async/await that don't break existing things, and make important changes to the runtime and package manager. Python's packaging is so broken that it's almost mandatory to have a Dockerfile nowadays, while in JS that's not an issue
