This probably isn't exactly what you want, but, unless you wanted to do
something especially with your own string class, I would just pass a
function to the sorted algorithm.
eg:
sorted( [a,b,c], cmp=lambda a,b: cmp(len(a),len(b)) )
gives you the below in the right order...

So it seems you have to redefine rich comparisons __lt__, __gt__,
__eq__ etc as well.

parameters of so
