decorator J4 - any objections?

Guido has said that he is open to considering *one* alternative 
decorator syntax.  At the moment, (Phillip Eby's suggestion) J4 

<URL: http://www.python.org/moin/PythonDecorators > (section 5.21 J4) 

looks very good to me -- and it is the only alternative without negatives.

   def func(arg1, arg2)
       @version("Added in 2.4")
       @returns(None)
   as:
       """Docstring could be here, or in decorator part above"""
       # body goes here

(Note the lack of colon on the func line; adding it would be more 
consistent and not hurt readability.)

   def func(arg1, arg2):
       @version("Added in 2.4")
       @returns(None)
   as:
       """Docstring could be here, or in decorator part above"""
       # body goes here

While I think this is the best solution so far, I realize that others 
have often disagreed with me on this issue -- so I would appreciate 
some feedback, particularly from those who don't like the J4 syntax.

Disclosure:  I like decorators on their own, but they are enough of 
a special case that I worry about cluttering up the language as a 
whole.  J4 seems the best compromise to me, but I could also make 
peace with Guido's current @proposal.
