I didn’t add that one. Recently I implemented some DOM interfaces,
including the multiple inheritance, using WebKit’s JSCore. It needed a
bit of hackery (since the public JSCore API is only designed for single
inheritance) but it worked in the end. That allowed user script to, for
example, do this:
var f = EventTarget.prototype.addEventListener;
var f2 = function(evt) { /* … */ };
assert(EventTarget.prototype != Node.prototype);
assert(typeof f == 'function');
assert(typeof Node.prototype.addEventListener == 'undefined');
assert(document.addEventListener == f);
EventTarget.prototype.addEventListener = f2;
assert(document.addEventListener == f2);
