I worked on an early digital telephone switch (at a competitor to Bell Labs), using a safe language with bounds checking. We estimated that the bounds checking cost us ~5-10% performance, and that it was a worthwhile price to pay for reliability -- what good is your performance boost if it's causing system crashes?

A few decades later, I see that Go (by someone from Bell Labs) has "invented" similar slices (I wonder if its compiler is as good as ours was at safely removing unneeded bounds checks).

@PeterLudemann Look I’ll gladly take a 5-10% performance hit *and* system crashes

@saagar You forgot to include integer overflow, for also getting wrong results; and as a bonus, hinders optimisations.
