I've attached a quick hack of an implementation, just to play with it  
and see how it feels.  Here's an example use:


from property import property


class Base(object):

     @property
     def attribute(self):
         print("Base.attribute (getter)")
         return 42

     @property.get(attribute)
     def rwattribute(self):
         print("Base.rwattribute (getter)")
         return self.attribute * 2

     @property.set(rwattribute)
     def rwattribute(self, value):
         print("Base.rwattribute (setter)")
         self.saved = value

class Derived(Base):

     @property.get(Base.attribute)
     def roattribute(self):
         print("Derived.roattribute (getter)")
         return self.attribute / 2
