I'm very tempted to check in my patch even though the PEP isn't
updated (it's been renamed from PEP 367 though). Any objections?
It is python.org/sf/1727209, use the latest (topmost) super2.diff patch.
This would make the new and improved syntax super().foo(), which gets
the class and object from the current frame, as the __class__ cell and
the first argument, respectively.
Neither __class__ nor super are keywords, but the compiler spots the
use of 'super' as a free variable and makes sure the '__class__' is
available in any frame where 'super' is used.
Code is welcome to also use __class__ directly. It is set to the class
before decoration (since this is the only way that I can figure out
how to generate the code).
The old syntax super(SomeClass, self) still works; also,
super(__class__, self) is equivalent (assuming SomeClass is the
nearest lexically containing class).
