Nice!

Why one list, though? Wouldn't a LoL be simpler to use AND easily let the user see how many ranges there are? Well, I guess they can do scalar(@diff)/5, but that doesn't seem as intuitive.

I don't know if the sublists would cause too much memory overhead, but it shouldn't be anywhere near as bad as the problem you cite with A::Diff.

That's just a nit; it's nice and clean, and quite useable as is.

Edit: Hmmm, nevermind. I guess if I want an LoL I can just do 

my @diff2;
while(@diff) {
    push @diff2,[splice @diff,0,5];
}
