I don't think Michel is saying they are worthless. However, the proposed syntax is highly contentious. It would be good if there was a short term solution that wouldn't require new syntax. That would give Guido and the Python community time to figure out the best syntax.

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.

No, that's a misunderstanding.. it was by coincidence alone that the last example I gave had two callbacks with an identical type signature. Using a "with" block for decorators is as nonsensical as this:

with args(x):

 def foo:
     pass

 def bar:
     pass
