          Once again, the solution is to use a special (typically private) 
          variable such as __XXX.

+ Note
+ 
+     The descriptor mechanism described in PEP 252 is powerful enough
+     to support this more directly.  A 'getset' constructor may be
+     added to the language making this possible:
+ 
+       class C:
+           def get_x(self):
+               return self.__x
+           def set_x(self, v):
+               self.__x = v
+           x = getset(get_x, set_x)
+ 
+     Additional syntactic sugar might be added, or a naming convention
+     could be recognized.
