BTW, I have no problem with the general direction of this change.  It makes a lot more sense to ask a synthetic child provider to change a value - since it does represent the value of the ValueObject - rather than the summary which is just some free-form text.  And being able to change characters in a string seems a reasonable thing to do, so switching the std::string comprehension from a Summary provider to a Synthetic Child Provider is the way to do that.  So that part if fine.  

But std::strings abound in code, and so if we're going to make this change I don't think we can make that printing less space efficient, which this change seems to have done.  We should figure out why that's the case and fix for this to be a really good change.
