//Write out src to console
console.log(src);

//The output of console.log(src)
src = function () {
    var what, a = arguments, L = a.length, ax;
    while (L && this.length) {
        what = a[--L];
        while ((ax = this.indexOf(what)) !== -1) {
            this.splice(ax, 1);
        }
    }
    return this;
} 

//Is This right or can it be done?
 src.attachEvent(goog.events.getOnString_(type), proxy)
