title: Get std::pair member using only standard function in C++03
body: <p>Is there a way, using only C++03 standard functions get a <code>std::pair</code> member, i.e. <code>first</code> or <code>second</code>? </p>
  
  <p>In C++11 I could use <code>std::get&lt;0&gt;</code> or <code>std::get&lt;1&gt;</code> respectively in this case.</p>
