title: How to get [[boundthis]] from function
body: <p>I need your help.<br>
  I have 2 functions:    </p>
  
  <pre><code>addMoveListeners: function(e) {
    e = e || window.event;
    // Binging context to function move
    moveListener = MYAPP.move.bind(e.target.parentElement);
    //
    if (e.target.classList.contains('move')){
      document.addEventListener('mousemove', moveListener, false);
      document.addEventListener('mouseup', MYAPP.removeListener, false);
    }
    resizeListener = MYAPP.resize.bind(e.target.parentElement);
    if (e.target.classList.contains('resize')){
      document.addEventListener('mousemove', resizeListener, false);
      document.addEventListener('mouseup', MYAPP.removeListener, false);
    }
    return false;
  },
  </code></pre>
  
  <p>and this:</p>
  
  <pre><code>removeListener: function(e){
    e = e || window.event;
    //Here I want get element from function
    console.dir(resizeListener);
    // Function stores it in [[BoundThis]]
    document.removeEventListener('mousemove', resizeListener, false);
    document.removeEventListener('mouseup', MYAPP.removeListener, false);
    document.removeEventListener('mousemove', moveListener, false);
    document.removeEventListener('mouseup', MYAPP.moveListener, false);
  },
  </code></pre>
  
  <p>How can I get property [[BoundThis]] from function resizeListener without execution.</p>
