title: Kotlin View setEnabled function missing?
body: <p>In <strong>Kotlin</strong>, when using <code>kotlinx.android.synthetic</code> to access the <code>View</code> (e.g. <code>Button</code>), the <code>setEnabled()</code> function is missing? The <code>isEnabled()</code> function is still there.</p>
  
  <p>How could I <code>setEnabled()</code>?</p>
