title: How to NOT a helper?
body: <p>What is the best way to perform a NOT operation?</p>
  
  <p>For example, here's the javascript</p>
  
  <pre><code>Template.mytemplate.helper({
    myhelper : function(){
      return true;
    }
  });
  </code></pre>
  
  <p>Now how would I get !myhelper in a template? I've been doing</p>
  
  <pre><code>&lt;template name="mytemplate"&gt;
    {{#if myhelper}}
    {{else}}
      myhelper is false
    {{/if}}
  &lt;/template&gt;
  </code></pre>
  
  <p>But there's gotta be a better way. I could create an equality helper and do <code>{{#if equal myhelper true}}</code> but that doesn't seem very clean.</p>
  
  <p>Does anyone have any better ideas?</p>
