[Python-Dev] Re: PEP 318: Decorators last before colon

[Peter Norvig]

I have to say I favor the "last before colon" approach, but if it has
to be before the def, then I think it should have a keyword, and if
you don't want to introduce a new keyword, then it looks like "is" is
the only reasonable candidate.  And if you do have a keyword, you
don't need the square brackets.  So you have

is: classmethod
def f(x): 
    pass


is: author("Guido"), signature(int, result=None)
def g(x):
    pass
