#include <string>
#include <iostream>

int main()
{

    std::istringstream one("one");
    std::ostringstream two("two");

    std::cout << "Before move, one = \"" << one.str() << '"'
              << " two = \"" << two.str() << "\"\n";

    *one.rdbuf() = std::move(*two.rdbuf());

    std::cout << "Before move, one = \"" << one.str() << '"'
