It is disgustingly specific, but at the same time it is much better than having the int coercion code in every function that coerces ints. I think something like this specific to a type is about the best you can do, but I'd loved to be proven wrong. Anyhow, I think my overarching goal was to fit this kind of thing into some sort of coercion framework along with standard canonical coercion or a new standard ...
