> But a buffer overflow like from the article? That's just a matter of saving the length of the array alongside the pointer and doing a bounds check, which a compiler could easily insert Both the array length and the index can be computed at runtime based on arbitrary computation/input, in which case doing bounds checks at compile time is impossible.
