Manually tested !

Extend the description with the following section :

<p>The with statement was intended to provide a shorthand in accessing properties in deeply nested objects. Unfortunately, it behaves very badly when setting new properties. Never use the with statement. Use a var instead.</p>

<pre>
var ooo.eee.oo.ah_ah.ting.tang.walla.walla.bing = true;
var ooo.eee.oo.ah_ah.ting.tang.walla.walla.bang = true;
</pre>

instead of 

<pre>
with (ooo.eee.oo.ah_ah.ting.tang.walla.walla) {
    bing = true;
    bang = true;
}
</pre>
