That WG21 made finally made its containers safer is great, but the C standard library does not have containers. You can still have your own bounds checked containers just fine in C, as you could in the past.. ISO C simply does not matter as much as you like to pretend - for trolling I must assume.

When we will have a standard for bounds checking arrays and pointers remains to be seen, but this does not stop anyone from using the non-standard tools available today.
