title: Reference variable equals another reference variable?
body: <p>Consider the following:</p>
  
  <pre><code>int someA = 1;
  int someB = 2;
  
  int &amp;a = someA;
  int &amp;b = someB;
  
  a = b;   // what happens here?
  </code></pre>
  
  <p>What's happening here with the references?  Just curious.</p>
