title: Is the comma in a variable list a sequence point?
body: <p>In the following type of code is there a sequence point between each variable construction, or is the result undefined?</p>
  
  <pre><code>int a = 0;
  int b = a++, c = a++;
  </code></pre>
  
  <p>I wasn't able to find in the standard a specific reference to a sequence point here. Does that mean it is undefined, or just that I failed in my search? The completion of an expression is a sequence point, but does the above initialization also count?</p>
