title: Interdependent initialization with commas?
body: <p>Is the following perfectly defined:</p>
  
  <pre><code>int x = 42, y = x;
  </code></pre>
  
  <p>i.e. strictly equivalent to:</p>
  
  <pre><code>int x = 42;
  int y = x;
  </code></pre>
  
  <p>EDIT : the question is not about style (I know that it's wrong...), the question is "theoretical"</p>
