The reverse argument is hard to defend too.  Is this code portable?

#include <sstream>

int main ()
{
        std::ostringstream s;
     s << "Hello, World!\n";
}

This code implicitly relies on basic_ostream defined in <ostream> and 
basic_ios defined in <ios>.  Since templated base classes can be derived 
from with merely a forward declaration of the templated base, it is not 
clear if <ostream> and <ios> are implicitly included.  If <ostream> is 
not included, then even the operator<<(const char*) won't be in scope!

I've never seen such a deviant implementation of the standard C++ lib, 
and hope I never do.  Most people (rightly) believe that if you include 
<sstream> then that's all you need to get ostringstream up and running.
