/**

* std::ostringstream wrapper.
|
|
*
|
|
* ostringstream's operator<< doesn't return a ostringstream&. It returns an
|
|
* ostream& instead. This is unfortunate, because it means that you can't do
|
|
* something like this: (ostringstream() << n).str() to convert an integer to a
|
|
* string, all in one line instead you have to use this far more tedious
|
|
* approach:
|
|
* ostringstream s;
|
|
* s << n;
|
|
* s.str();
|
|
* This class corrects this shortcoming, allowing something like this:
|
|
* string result = (formatter() << "blah " << n << x << " blah").str();
