Oooh yuk. How horrible. I'd rather that didn't happen. For one thing,
it means that empty arrays (and empty collection ranges generally)
would have to have a different representation.

No, I like the "standard" way of doing things, whereby the end
iterator refences the last+1 element (and therefore cannot be
dereferenced).
