Personally, I think the whole const-final-invariant thing is quite a bit nicer than any other implementation I've seen: being able to mark an object as invariant makes writing threadsafe code a lot easier. If there was a way to mark a class/struct as "invariant after being constructed," then it'd be unbeatable.

Frankly, I expect to be casting stuff to invariant constantly, based on 
the current design.
