Is that conceptually clean/clear? (If so, I'd like to request an array of 
length -1.)

I like Andrei's proposal because it keeps clarity in such cases: sizes 
are non-negative quantities. Once you start subtracting ints, it's 
possibly not a size anymore, in such cases you want the user to decide 
explicitly.
