title: Meteor: Access Template Helper (or variable) from another helper
body: <p>How can I reference a template helper from another one? For example...</p>
  
  <pre><code>Template.XXX.helpers({
      reusableHelper: function() {
          return this.field1 * 25 / 100; //or some other result
      },
      anotherHelper: function() {
          if (this.reusableHelper() &gt; 300) //this does not work
              return this.reusableHelper() + ' is greater than 300'; 
          else
              return this.reusableHelper() + ' is smaller than 300';
      }
  });
  </code></pre>
  
  <p>I have also tried Template.instance().__helpers.reusableHelper - all with no luck.</p>
  
  <p>Alternatively is there a way to define reactive Template instance variables?</p>
  
  <p>XXX is a sub-template that renders multiple times on the same page.</p>
