Breaks scope.

We should be seeing this alerted:

yup!
[Object Window]
function a() ...
function a() ...
function a() ...
true
Bluebird of happiness

(run it through firefox, it will gives this result).
However, we instead get this:

yup!
[Obejct Window]
undefined
function a()...
undefined
true
Bluebird of happiness

The strange thing is that "this" really thinks its window, but it doesn't
behave like it since a() doesnt get registered into window.

If you comment out the r function, so that everything that happens is global,
like this:

<script>

alert("yup!");

//function r()
//{
    var predefined_js= "alert(this);function a(){alert('bluebird of
happiness');}alert(this.a);alert(a);alert(window.a);alert(this===window);";
    var main_js= "eval.apply(window, [predefined_js]); main= function() { a();
return 0; }";

    eval.apply(window, [main_js]);
//}

//r();

main();

</script>

Now it works as it should.
