Perhaps. My argument is that anything that introduces a new class-like
construct and set of lexical scoping rules is a language change. For
example, if this change went into 2.7.13 would Jython suddenly be broken
because it hasn't implemented the new scoping rules?
It's not a language change*. There is nothing for Jython, IronPython,
Brython, etc., to implement. No scoping rule changes, nothing. The
magic in Steven's name space is implemented by the metaclass by
(presumably) rebuilding all the functions -- and that is how he manages
the effective scoping rules.

*Okay, it is not a language change the same way the addition of Enum was
not a language change. On the other hand, asyncio did have some
language changes (await, async, etc.).
