It would be really spiffy if the decorator were able to run the decorated 
function and then have access to the function's locals dictionary. It would 
then be possible to define a property like so: 

class Foo(object): 
    def bar(self) [property]: 
        """ bar property docstring """ 
        def get(self):  
            return self.__bar 
        def set(self, bar): 
            self.__bar = bar 

The property decorator would reach inside the locals dictionary amd pull out  
the special names 'get', 'set' and 'delete', and use them to construct the 
property descriptor.
