I just checked this, to find that what the construct will actually do is:

temp = new Object();
temp.radius = 1;
temp.position= [0,0,1];
Sph = new Sphere(temp);

This also matches what the ISO ECMAScript specification implies.

So at the point e.g. the "position" property is set, it will still use the
standard getter/setter mechanism of the basic Object type.

Furthermore, it will not act on the Sphere object at all - it will just create
yet another object that will be passed as one single parameter to the Sphere
object.
