title: Angular not defined when trying angular2?
body: <p>I am trying out angular2 in the ES5 way with this code:</p>
  
  <pre><code>&lt;html&gt;
      &lt;head&gt;
              &lt;script src="https://code.angularjs.org/2.0.0-alpha.31/angular2.sfx.dev.js"&gt;&lt;/script&gt;
              &lt;script&gt;
              function AppComponent() {}
  
              AppComponent.annotations = [
                  new angular.Component({
                          selector: 'my-app'
                  }),
                  new angular.View({
                          template: '&lt;h1&gt;My first Angular 2 App&lt;/h1&gt;'
                  })
              ];
  
              document.addEventListener('DOMContentLoaded', function() {
                angular.bootstrap(AppComponent);
              });
              &lt;/script&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;my-app&gt;&lt;/my-app&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>In chrome I am getting the nasty error:</p>
  
  <pre><code>Uncaught ReferenceError: angular is not defined
  </code></pre>
  
  <p>Specifically with the line that says: </p>
  
  <pre><code> new angular.Component({
  </code></pre>
