Reference loops
<p>I don't know how better to describe this. So take this example.</p>

<pre><code>var a = {
  x: 1,
  y: 2 };

var b = {
  z: 3,
  refA = a };

a.refB = b;
</code></pre>

<p>I have a preference that this is sort of behavior is ugly.  So at best, I have a personal disagreement with this sort of coding.  You should not need to have these types of references, and it leads to code that is difficult to comprehend.  </p>

<p>However, does anyone see a technical penalty for doing these sort of references.</p>
