title: Compare size (Count) of many lists
body: <p>I was wondering if I can compare size of many lists in a elegant and fast way.</p>
  
  <p>Basically this is my problem, I need to assert that 6 lists have the same size. So the usual way is something like (warning ugly code..):</p>
  
  <pre><code>if (list1.Count == list2.Count &amp;&amp; list1.Count == list3.Count &amp;&amp; .....) {
      //ok, so here they have same size.
  }
  </code></pre>
  
  <p>Some Jedi alternatives here?</p>
