In other words, the plan is to pretty much deprecate Object? I 
hope there would be appropriate replacement before this happens. 
Users should be able to have a standardized API and a default 
implementation for these methods.
Is phobos going to introduce interfaces such as Printable, 
Comparable, etc.. ? (names tentative, I'm more worried about the 
semantics).
