In ES6 speak, we have split the "new Foo(...args)" expression into

So in particular this allows creation of "uninitialized" instances in
some sense, yes?
function MyButton() {
HTMLButtonElement.call(this);
This won't work right given how HTMLButtonElement is currently defined
in WebIDL. Need to fix that at the very least.
MyButton.prototype = Object.create(HTMLButtonElement.prototype, {
...
});
document.register(‘x-button’, MyButton);
And the point is that document.register changes the [[Construct]] of
MyButton but does nothing else with it?
What happens if the same function is registered for several different
tag names, in terms of what happens with the [[Construct]]?

Define, please. How does one determine this, in a rendering engine
implementation? I certainly have no way to tell, in Gecko, when I'm
"entering script", offhand....
