I don't understand what it does in an inversion of control article, because it's just the opposite of IoC. Further more, instead of trying to actually manage your dependencies by giving components the signatures that document the exact things they need, you just gonna give them a "locator" that depends on everything under the sun? How is that dependency "management" or any sort of "pattern"?
