title: Why doesn't nodelist have forEach?
body: <p>I was working on a short script to change <code>&lt;abbr&gt;</code> elements' inner text, but found that <code>nodelist</code> does not have a <code>forEach</code> method.  I know that <code>nodelist</code> doesn't inherit from <code>Array</code>, but doesn't it seem like <code>forEach</code> would be a useful method to have? Is there a particular implementation issue I am not aware of that prevents adding <code>forEach</code> to <code>nodelist</code>?</p>
  
  <p>Note: I am aware that Dojo and jQuery both have <code>forEach</code> in some form for their nodelists.  I cannot use either due to limitations.</p>
