title: Android Studio and Kotlin: Unresolved reference: also
body: <p><a href="https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/also.html#also" rel="noreferrer">also</a> compiles and runs from Android Studio:</p>
  
  <pre><code>val greeted = "World".also { println("Hello $it") }
  </code></pre>
  
  <p>Yet the editor highlights <code>also</code> and <code>it</code> as errors and don't give any help with intellisense. <a href="https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/apply.html#apply" rel="noreferrer">apply</a> still works and when I go to source I can see the definition of both <code>apply</code> and <code>also</code>. How do I get Android Studio to recognize <code>also</code>?</p>
  
  <ul>
  <li>Android Studio 2.3.3</li>
  <li>kotlin_version = '1.1.3-2'</li>
  <li>Kotlin plugin 1.1.3-release-Studio2.3-2</li>
  </ul>
  
  <p>I've also had this problem with earlier versions.</p>
