Phillip J. Eby:

'as' is not currently a keyword, and making it so would break any programs that use it as a name.

It has been documented as a pseudo-keyword for some time, with the warning that it will may become a real keyword later.

Really, of the current "before the def" proposals, I think I like Samuele's:

*[classmethod]
def func(*args):
     pass

approach the best.  The '*' seems to say "special note, pay

attention". :)

I agree that it says special note; it just doesn't say why the list is special. We happen to know that it secretly means 

"After you evaluate this list, keep a reference, then 
call each member on the function or class I'm about to
define."

but a keyword (even as) makes it more explicit why this list is special. Of course,

as:  d1, d2, d2
def func(args):
   pass

also works; if you put a keyword at the front, then [] becomes redundant. And that was one of the bakeoff options, except that Guido used "decorate:" instead of "as:" in his example.
