Access a variable in an object from an encapsulate one
<p>The title is a little ambigous but the code explains the issue very clearly:</p>

<pre><code>function Game() {
    this.secret = '';
    this.Playground = {
        this.someTreat: function() {
            console.log('how to access secret from here ?');
        }
    };
}

var Test = new Game();
Test.Playground.someTreat();
</code></pre>

<p>I provide a <a href="http://jsfiddle.net/gzSt5/4/" rel="nofollow">JSFiddle</a> with this same code.</p>
