title: Is it possible to send multiple messages on one event using elm-html?
body: <p>I would like to send two messages to distinct adresses on one event.
  Particular case I encountered was that I had a some popup and when user clicks "Add" I would like to:</p>
  
  <ul>
  <li>Close the popup (message send to popup component)</li>
  <li>Inform parent component that item should be added (message send to parent component)</li>
  </ul>
  
  <p>onClick has following type "Address a -> a -> Attribute" some there seems to be no possibility to do that. On the other hand it seems like such pattern (one action resulting in multiple message) would be often met in practice.</p>
  
  <p>For now I resorted to sending one message informing parent about item added and then parent in update function updates popup with Hide action. </p>
  
  <pre><code>addButton = button [onClick context.addTaskAddress model.taskDescription] [text "Add"]
  </code></pre>
  
  <p>and then in parent's component update function</p>
  
  <pre><code>popup = AddTaskPopup.update AddTaskPopup.Hide model.popup
  </code></pre>
