among the libraries currently in boost, stringstreams are used by :

-test_tools, using wrap_stringstream

- math/quaternion.hpp and octonions, and date_time. It seems those use
stringstreams but could use wrap_stringstream just as well

- spirit which does its own wrapping of str/string stream (at first
glance it looks as if it could use wrap_stringstream instead)

-lexical_cast, which handles internally either strstreams or
stringstreams. I think it could also use wrap_stringstream.

- boost::format. stringstreams are in fact a performance bottleneck for
format, and I wrote an alternative stringstream class supporting most
platforms, to overcome std::stringstream limitations (making it possible
to reuse stringbufs, and the likes). BTW I'm also asking for opinions on
the status to give to this class, see
<1082886685.5949.42.camel_at_marvin.localdomain>)

It seems to me most libraries that need stringstream features only use
the basic interface (operator<< and then str() ) and could just as well
use wrap_stringstream.

About the code :
I'm wondering, why have the str() function return a const-reference to
string rather than a value, like stringstream does ?
