it has been proposed before, but there was no conclusive answer last time:
is there any chance for 2.5 to include commonly used decorators in a module?

Of course not everything that jumps around should go in, only pretty basic
stuff that can be widely used.

Candidates are:
 - @decorator. This properly wraps up a decorator function to change the
   signature of the new function according to the decorated one's.

 - @contextmanager, see PEP 343.

 - @synchronized/@locked/whatever, for thread safety.

 - @memoize

 - Others from wiki:PythonDecoratorLibrary and Michele Simionato's decorator
   module at <http://www.phyast.pitt.edu/~micheles/python/documentation.html>.

Unfortunately, a @property decorator is impossible...
