Summary: Deferred String Addtion:  Proof-of-concept

Initial Comment:
The attached patch demonstrats a possible
implementation for 
deferred string addition.  The idea is to have
str.__add__ save references to its inputs rather that
do the concatenation immediately.  The moment some
other method needs the full string, it is generated
recursively so that the whole concatenation can be done
with a single join.
