title: Default stringify for objects, equivalent to Java's toString?
body: <p>I have just take a look at the 3º tutorial from dart, creating the rating component. I was wondering if there is same method which is called when stringifying an object, something similar to Java's toString.</p>
  
  <p>For example:</p>
  
  <pre><code>MyClass myObject = new MyClass();
  System.out.println(myObject);
  </code></pre>
  
  <p>Will call MyClass.toString() if overwriten, else will call it's parent until java.lang.Object is reached giving a default toString.</p>
  
  <p>I find kind ugly (completely subjective) doing:</p>
  
  <pre><code>&lt;span ng-repeat="star in cmp.stars" &gt; {{star.toString()}} &lt;/span&gt;
  </code></pre>
  
  <p>I would rather do:</p>
  
  <pre><code>    &lt;span ng-repeat="star in cmp.stars" &gt; {{star}} &lt;/span&gt;
  </code></pre>
  
  <p>And give the implementation of how I want it to display at an averwritten method. Is this possible?</p>
