Name of class instance

Hi,

I'm wondering if it's possible for an object to figure it's name.
for example:

function baseClass() {
	// setup properties of "baseClass"
}
baseClass.prototype = {
	aMethod: function() {
		// do something using the name of the object
		// that's an instance of this (or derived) class
		// e.g.
		// window.alert('my name is: "' + DUNNO + '"');
	};
};

function childOne() {
	// setup properties of "childOne"
}
childOne.prototype = new baseclass();

function childTwo() {
	// setup properties of "childTwo"
}
childTwo.prototype = new baseclass();

var o1 = new childOne(), o2 = new childTwo();

Now when calling "o1.aMethod()" the "DUNNO" should be "o1" and the
same with "o2" respectively.

Is that possibly without having to force a "name" argument down the
inheritance tree?
