I am not advocating this, but this could be:

def abs(self):
   with self:
     with math:
       return sqrt(x**2 + y**2 + z**2)

The idea being that "with self" use 
creates a new namespace:
   newGlobal= oldGlobal + oldLocal
   newLocal= names from self

Similarly, "with math" creates a newer 
namespace:
   newerGlobal= newGlobal + newLocal
   newerLocal= names from math

My guess is that there would be little 
use for nesting the
"with".
