title: No ConvertAll for LinkedList<T>?
body: <p>Does anyone have an extension method to quickly convert the types in a <code>LinkedList&lt;T&gt;</code> using a <code>Converter&lt;TInput, TOutput&gt;</code>?</p>
  
  <p>I'm a bit surprised, where is the <code>ConvertAll&lt;TOutput&gt;(delegate)</code>?</p>
