Well, it has been done with Bohem.

But anyway I wrote up my sketch design in my blog:

It is more like bounds checking than a new type. Sure, I do 
propose a new type, but just to locally bypass the thing, not as 
something mandatory. With a compiler switch, you can turn it on 
or off to experiment with different strategies.
