A probably evil hack to get working super in any function.
// Add a handy super call for all objects
MyBaseClass.prototype.super = function () {
var parent = this.__proto__.__proto__;
var caller = arguments.callee.caller;
var fn;
if (caller.prototype === this.__proto__) {
fn = parent.constructor;
} else {
// This is probably quite slow, but it doesn't seem to affect
// performance too much in real tests.

How to detect whether a hash change came from the Back or Forward button
