title: Scala 2.11 LinkedList is deprecated, what should I use?
body: <p>According to <a href="http://www.scala-lang.org/api/current/index.html#scala.collection.mutable.LinkedList">the docs</a>, <code>scala.collection.mutable.LinkedList</code> is deprecated as of the 2.11 version. Unfortunately I have found nothing to replace it with. I need an ordered collection that can remove an item from <strong>any</strong> index in constant time.</p>
  
  <p>What should I use?</p>
