This is what I had in mind:

TU1:
========================================================================
#include <iosfwd>
#include <string>

void f(std::ostream &os, const std::string &s) {
  os << s;
}
========================================================================

TU2:
========================================================================
#include <iostream>
#include <string>

using namespace std;

void f(ostream &os, const string &s);

int main() {
  f(cout, "hello world");
}
========================================================================

I believe this is conforming, but I may be mistaken.

Thanks,
