This has two primary consequences: 10*4d6fc14bSjoergfirst, functions might not report precondition violations by throwing. 11*4d6fc14bSjoergSecond, user-provided functions, such as custom predicates or custom 12*4d6fc14bSjoergtraits, which throw might not be propagated up to the caller (unless 13*4d6fc14bSjoergspecified otherwise by the Standard). 14
