title: Object (string or array) NAME. how to get it?
body: <p>I need a prototype done in this way:</p>
  
  <pre><code>Array.prototype.getname=function(){ [...]return arrayname; }
  </code></pre>
  
  <p>So I can:</p>
  
  <pre><code>z=new Array;
  alert(z.name);
  </code></pre>
  
  <p>and I should have "z" in the alert.</p>
  
  <p>I'm working on Chrome and caller/callee seem to return empty.</p>
