[v8-users] Does changing the type passed to a constructor change a hidden class (and other queries)?

[Wyatt]

With the follow code one hidden class is created:

function Point(x, y) { 
    this.x = x;
    this.y = y; 
}
var p1 = new Point(11, 22);
var p2 = new Point(33, 44);

Will p2.x="aString"; change its hidden class?

Will p2.x=undefined; change its hidden class?

Will p3= new Point(42,"theAnswer"); create a new hidden class?

I'm inclined to think that the answer is yes for each case..?
Or at least each of these cases seems as if it could not be fully optimized.

Any help is much appreciated!
