No it's not, they confuse "undefined behavior" with "hard to analyse behavior" for starters. Exceptions are not UB, but the control flow is totally not obvious.

No it's not, they confuse "undefined behavior" with "hard to analyse behavior" for starters. Exceptions are not UB, but the control flow is totally not obvious. If I were to start a project today, I'd rely heavily on optional and result types and use exceptions only for serious errors, when it makes sense to unwind ans start from a clean slate.
