title: access object property in handlebar contains '.'
body: <p>I am getting data from service in which  array of objects are coming like below:-</p>
  
  <pre><code>    [{
          title : 'Tilte 1',
          s.no : 1
       },
       {
          title : 'Tilte 2',
          s.no : 2   
       }
      ]
  </code></pre>
  
  <p>I have used handlebars templating to parse this data like below:-</p>
  
  <pre><code>{{#each this}}
     &lt;div&gt;
        &lt;span&gt;{{this.s.no}}&lt;/span&gt;
        &lt;h2&gt;{{this.title}}&lt;/h2&gt;
     &lt;/div&gt;
  {{/each}}
  </code></pre>
  
  <p>In the above I am not able to access the property('s.no'). In vanilla JavaScript we can access it like this['s.no'] but in handlebars it's not working.</p>
