I worked (a long time ago) on Burroughs mainframes which did bounds checking of arrays (and in fact even type checking), because the whole machine was build around ALGOL. I am not sure whether the experience from these machines was negative. It may be that when you move beyond one-dimensional arrays, bounds checking becomes more complicated. Perhaps performance suffers too. Languages which do bounds checking often have intelligent compilers which can skip the bounds check in a variety of conditions. So even if the hardware is faster, it may be doing unnecessary checks.
