title: javascript variable reference/alias
body: <p>Is it possible in javascript to assign an alias/reference to a local var someway?</p>
  
  <p>I mean something C-like:</p>
  
  <pre><code>function foo() {
    var x = 1;
    var y = &amp;x;
    y++;
    alert(x); // prints 2 
  }
  </code></pre>
  
  <p>= EDIT =</p>
  
  <p>Is it possible to alias arguments.callee in this code?:</p>
  
  <pre><code>function foo() {
    arguments.callee.myStaticVar = arguments.callee.myStaticVar || 0;
    arguments.callee.myStaticVar++;
    return arguments.callee.myStaticVar;
  }
  </code></pre>
