title: Sequence-before relation in comma-separated variable definitions
body: <p>Let's begin with the following example code:</p>
  
  <p><code>int a = 0, b = a++, c = a;</code></p>
  
  <p>Is <code>a++</code> sequenced before <code>a</code> (within <code>c = a</code>)? <code>a++</code> and <code>a</code> seem to qualify as full expressions, and according to <a href="http://en.cppreference.com/w/cpp/language/eval_order" rel="nofollow">cppreference</a> (Rule 1), the answer should be positive. But I'm not sure.</p>
