What is the point of a = a;? Analysing the jQuery source
<p>From the jQuery <a href="http://code.jquery.com/jquery-1.7rc1.js" rel="nofollow">1.7rc1 source code</a> (lines 1822-24):</p>

<pre><code>if ( jQuery.isArray( name ) ) {
        name = name;
}
</code></pre>

<p>What's the point of having <code>name = name</code>? Could the two <code>name</code>s be different?</p>
