title: Convert List of Ints to a SortedSet in Scala
body: <p>If I have a List of Ints like:</p>
  
  <p><code>
  val myList = List(3,2,1,9)
  </code></p>
  
  <p>what is the right/preferred way to create a SortedSet from a List or Seq of Ints, where the items are sorted from least to greatest?</p>
  
  <p>If you held a gun to my head I would have said:</p>
  
  <p><code>
  val itsSorted = collection.SortedSet(myList)
  </code></p>
  
  <p>but I get an error regarding that there is no implicit ordering defined for List[Int].</p>
