title: TypeError: boolean is not a function
body: <p>I'm using SocketStream.</p>
  
  <p>I'm calling <code>@session.save cb response</code></p>
  
  <p>The error doesn't happen until I pass response into the callback.</p>
  
  <p>response is...</p>
  
  <pre><code>{ success: true,
    attributes: 
     { _id: 00000000,
       email: 'test@example.com',
       type: 'example' 
     }
  }
  </code></pre>
  
  <p>Any ideas?</p>
  
  <p>The callback is fired and everything works. The server just crashes with TypeError: boolean is not a function</p>
