I'm not necessarily a fan of the idea of allowing you to iterate over an `IncompleteRange`, but I have to ask: What do you imagine an infinite sequence of integers would do when it tried to go past the `max` value? As far as I can tell, trapping is the *only* sensible possibility.

(If you used a `BigInt` type, the sequence could of course then be infinite, or as infinite as memory allows.)
