That's one reason, but even more importantly this gives the 
implementation more freedom and potentially more options for 
client code. I haven't added it yet (mostly due to laziness) but 
I considered compile-time policies to inline the vtable in the 
object, or to determine ordering of the vtable and the 
implementation (might have performance considerations), and a few 
other things.

Also: more fun to implement, and shows that it can be done as a 
library.
