Likely because it does bounds checking, so you at least know that it's not
null. But I don't see why that would really improve much considering that
the odds are that you're really going to be accessing far more than just the
first element with the pointer. It seems _slightly_ better from a safety
perspective but only slightly. So, I don't know what the point is in
suggesting it as an alternative.
