That seems kind of strange. It seems even strange to me that methods
(replete with implementation) can be added to the interface's
prototype, in implementation code, and that this actually gives the
object the method.

I take it you mean "how to handle method calls, where the argument is
shorter than the number of formal parameters."

That could be complicated.

Either throw an error or have the "false-ish" value conversion of
undefined, or assume a default value if not specified. Hypothetical
examples:

addEventListener( document, click ); // use capture is undefined,
default is false.

initMouseEvent(type, canBubble, cancelable, view,
                     detail, screenX, screenY, clientX, clientY,
                     ctrlKey, altKey, shiftKey, metaKey,
                     button, relatedTarget);

(I always forget those long string of boolean args).

Too bad relatedTarget is last. I think the canBubble argument being
second was not the best choice, AFAIK mouseevents always bubble (until
propagation is stopped. that is).

There's cloneNode( deep ); If deep were omitted, it could be false?
