I guess we’re violently agreeing? Exceptions are an order of magnitude (or several orders) slower than function calls and returns; but that can still be efficient overall, if only a tiny fraction of calls fail.

I’d simply add that most people greatly underestimate how expensive exceptions are, even in C++.

Calling the destructors is identical to ending any scope in C++, including function calls. Where is that extra expense?

You likely have to parse exception blocks and maybe chase pointers to find the objects to destroy. In the happy path, you can just call the destructors directly.
