How to create a new window object without iframe?

How can I create a new object Window, myWindowwhich is independent of Window(so the change, for example, myWindow.Array.prototypedoes not affect window.Array.prototype), without creating <iframe>?

I am currently doing this as follows

function newWindow(){
    var myFrame = document.createElement('iframe'), myWindow = undefined;
    myFrame.style.display = 'none';
    myFrame.src = 'javascript:undefined;';
    document.body.appendChild(myFrame);
    myWindow = myFrame.contentWindow;
    document.body.removeChild(myFrame);
    return myWindow;
}

Ultimately, I would like to make my own copies of the main types of objects and prototype them.

Umm ... you can't do this. Well ... you can call window.open, but it will open a new window. And ... why do you need this? Sounds like you're wrong.

function augmentArray(a) {
  a.purgeAll = function() {a.length = 0;};

var myList = [1, 2, 3];
augmentArray(myList);
myList.purgeAll();
