i’m trying to add the prototype methods of twoClass to the protype methods of oneClass like this:

```auto

Function.prototype.extend=function(superclass){
	this.prototype. __proto__ =superclass.prototype; };

twoClass.myFunc=function() //pseudo ext

twoClass.extend (oneClass);
//twoClass and oneClass are class constuctors

```

i think i should be able to call a prototype method in twoClass the same way it’s called in oneClass:

```auto

myObj=new (oneClass) //pseudo ex

myObj.myFunc(); //calls function inherited from twoClass

```

unfortunately, it’s not working for me right now–can anybody show me the method for adding one classes’ prototype functions to anothers? mucho obligato…
