title: Kotlin: Cannot declare a argument of type mutableListOf in class definition
body: <p>I cannot use the <code>mutableListOf</code> in the constructor. But I can use it in the 
  class body. Is this a known bug or just we cannot do it this way?</p>
  
  <p>Here is my code:</p>
  
  <pre><code>class Model (val title: String, var listString: kotlin.collections.mutableListOf&lt;String&gt;, var selectedIndex: Int = 0) : FormFieldModel(FormFieldType.SELECT_BOX) {
      var iad = mutableListOf&lt;String&gt;()
  }
  </code></pre>
  
  <p>And I get <code>Unresolved reference: mutableListOf</code> in the constructor.</p>
