No apologies necessary! I was just pointing out how you might figure it out
on your own. Teach a man to fish and all that...

Object (which is a function) .extend will add forEach to the Object
namespace. Object.implement will add forEach to the prototype (as you note).
Extending the object prototype is a *bad* idea. See:
