I feel slightly misrepresented. I explained how exceptions are implemented, and the actionable intelligence you can derive from that understanding (if perf matters to your code and/or scenario, then use exceptions only for hard errors, not for generic signaling). If perf does not matter in your scenario, than obviously the guidance does not apply to you. To me that does not mean it's a waste of time to explain how exceptions work and what that means to performance critical code.
