We've been discussing this off and on for OVER A YEAR! If 'the best syntax' hasn't been figured out yet after N thousand emails on the subject, I see no reason to believe enlightenment is going to arrive soon (or ever). There's no particular reason to believe that effort alone will arrive at an elegant solution. On the other hand, maybe there isn't a good syntax for arbitrary decorators.

Has something along these lines been discussed?

with [staticmethod, classmethod]:

 def foo(x):
     pass

 def bar(x):
     pass

IIUC, the PyObjC application needs whole swathes of functions with the same decoration, but this syntax isn't much worse for one function than for many.
