title: AS3 - for (... in ...) vs for each (... in ...)
body: <p>The following code does the exact same thing. Is there a difference between <code>for each</code> and <code>for (... in ...)</code>?</p>
  
  <pre><code>var bar:Array = new Array(1,2,3);    
  
  for (var foo in bar){
      trace(foo);
  }
  
  for each (var foo2 in bar){
      trace(foo2);
  }
  </code></pre>
