For current stdlib features and types like vector that aren't thoroughly bounds-checked, the objective is for these options to become bounds-checked when identified as from code While using the bounds profile on, and unchecked when named from legacy code, quite possibly using contracts (concurrently remaining proposed by quite a few WG21 associates).
This would become a list of alterations across the whole code base, but would almost certainly have massive Advantages.
(Not nonetheless enforceable) A language facility is less than specification. When the language facility is on the market, warn if any non-variadic template parameter is just not constrained by an idea (in its declaration or pointed out in a very demands clause).
