Javascript eval on global scope?

Question

Is it possible to use the eval command to execute something with a global scope? For example, this will cause an error:

Answer 1

(function(){
    eval.apply(this, arguments);
}(a,b,c))

This will invoke eval using the global object, window in browsers, as the this argument passing any arguments you've passed into the anonymous function.

eval.call(window, x, y, z) or eval.apply(window, arguments) is also valid if you're certain window is the global object. This isn't always true, however. For instance, the global object in a Node.js script is process if I remember correctly.
