Just so this suggestion doesn't get buried in the part of the thread where I was 
getting rather carried away about Greg's 'of' syntax (sorry!).

What about:

   result + x**2 from result = 0.0 for x in S

Essentially short for:
   result = 0.0
   for x in S:
     result = result + x**2

Cheers,
Nick.
