I expect that at the moment, range+algorithms code will likely be somewhat
slower than old fashioned loops. This is because code generators have been tuned
for decades to do a great job with loops.
There's no intrinsic reason why ranges must do worse, so I expect they'll
achieve parity.
Ranges can move ahead because they can reduce the algorithmic complexity,
whereas user written loops tend to be suboptimal.
