FUD.
Will this code breakage "scare" them and slow down migration to new versions of python? They are already afraid of going 2.0(?). It is maybe just PR matter but ...
More FUD.
but FUD is what we have to deal with on the market.
I know from my 2.0 experiences that lots of people are concerned about even small changes (more ways to do it isn't always what a large organization wants). Pointing out that "hey, it's a major release" or "you can ignore the new features, and pretend it's just a better 1.5.2" helps a little bit, but the scepticism is still there.
And here we have something that breaks code, breaks tools, breaks training material, and breaks books.
"Everything you know about Python scoping is wrong. Get over it".
The more I think about it, the less I think it belongs in any version before 3.0.
