This is really only useful sometimes.

It is important to notice that if you do

class C : I {}

I c = new C();
c.something();


the template this there will show I, not C. All it means is this 
is being called on an object of that *static* type. So it isn't 
really a substitute for traditional virtual functions.

Sometimes appropriate to use, just often not.
