title: Weird bug or something in jquery plugin
body: <p>All of my elements which init by my jquery plugin sharing the same local variable when it running. I did a test and found out because this line:</p>
  
  <pre><code>var tmp1 = tmp2 = weird_local_var = 0;
  </code></pre>
  
  <p>If I write like below, it does not happens</p>
  
  <pre><code>var normal_local_var = 0;
  </code></pre>
  
  <p>It is not because tmp1 &amp; tmp2, just dummy var for testing. You can see the test via <a href="http://jsfiddle.net/7SeRD/" rel="nofollow">http://jsfiddle.net/7SeRD/</a>. What happen?</p>
