title: Random shuffle not working for Range
body: <p>Scala version 2.10.3 running on java 7</p>
  
  <pre><code>import scala.util.Random
  Random.shuffle(0 to 4) // works
  Random.shuffle(0 until 4) // doesn't work
  </code></pre>
  
  <p>:9: error: Cannot construct a collection of type scala.collection.AbstractSeq[Int] with elements of type Int based on a collection of type scala.collection.AbstractSeq[Int].</p>
  
  <p>The error message seems to really only tell me "You can't do that".  Anyone have any insight as to why?</p>
