Compilers are, in my experience, better at optimizing i < n loops than they
are at optimizing i != end loops. They are better at constant-folding the n,
too, which then helps with eventual unrolls. But why are we having this
discussion at all? These are private members of the class; the author can do
whatever he likes.
