Would these be preferable:?

     class C(object):
         [property]
         def x(self): return self.__x

         [property_setter(x)]
         def x(self, val): self.__x = val

         [property_deleter(x)]
         def x(self): del self.__x
and:
     [generic(None, (int,int))]
     def f(x,y): print 'two ints'

     [generic(f, (float,float))]
     def f(x,y): print 'two floats'

I.e., explicitly pass the old value in, rather than grabbing it from 
sys._getframe.

Advantages:
   - no sys._getframe magic
Disadvantages:
   - you have to type the property/function name twice
   - you have to do something special for the first def
   - you can't easily rearrange the defs
