     Something not yet mentioned in this thread - the Qt QString provides
     a reference-counted "shallow-copy", (deep-copy on modification)
     mechanism that makes QString a lot more efficient than std::string
     in this kind of situation.  Copying a QString is cheap, and
     sizeof(QString)==sizeof(int).

     Has there been any boost proposal for alternative strings
     to std::string?
