I can't understand why we can't have a new keyword for decorators.
If I remember correctly the introduction of yield didn't result
in such a public outcry. We'd have to change our programs once
if a variable names collides with the new keyword, but that's better
than having to look at @s for the rest of our Python days.
So how about:
make classmethod
def foo(cls, bar):
