title: Scalactic: convert an Iterable to Every
body: <p>Using scalactic, one can convert an <code>Every</code> to a <code>List</code> like this:</p>
  
  <pre><code>scala&gt; Every(1,2,3).toList
  res6: List[Int] = List(1, 2, 3)
  </code></pre>
  
  <p>How can I perform the reverse operation, though, i.e. try to convert a <code>List</code> or an <code>Iterable</code> to an <code>Every</code>? Is there a built-in method that does this?</p>
