FWIW, there's prior art for something like Josiah's approach in the form 
of Java's StringBuilder & StringBuffer classes [1].

A mutable container is used to build the string, then converted to a 
normal immutable string when complete (this is similar to the intended 
use of collections.defaultdict, with the default in place during 
initialisation, but removed before the dictionary is given to any other 
part of the program).

Cheers,
Nick.
