A properly-developed library expresses intent (what is to generally be carried out, rather then just how a thing is currently being accomplished) considerably much better than immediate use of language characteristics.
For current stdlib features and types like vector that are not completely bounds-checked, the goal is for these characteristics to be bounds-checked when referred to as from code Using the bounds profile on, and unchecked when called from legacy code, quite possibly working with contracts (concurrently getting proposed by many WG21 customers).
We could convert code “base up” setting up with the rules we estimate will give the best Added benefits and/or maybe the least difficulty in a provided code base.
