title: How to create jQuery object from array of jQuery objects?
body: <p>Let's say I have an array of jQuery objects and wish to have one compound jQuery object instead.</p>
  
  <p>What would be the solution other than manual traversing an array and appending the elements to the just created jquery object using <code>.add()</code>?</p>
  
  <p>This doesn't do what I want:</p>
  
  <pre><code>var a = $('#a'),
      b = $('#b'),
      c = [a, b];
  
  // the lines above is the set up, they cannot be changed
  var d = $(c);
  d.hide();​
  </code></pre>

  <p>The expected result is both divs are hidden.</p>
  
  <p>Any ideas?</p>
