Ah, OK; basically I agree with that. Checking for a rarely occurring
error at multiple levels of block or function call nesting is expensive
compared to not having to do that at all due to exceptions taking care
of it.

(I take it for granted that code that exists and is executed is almost
always slower than code that doesn't exist. I say almost, because I'm
always prepared to be delighted by reports of highly weird circumstances.)

I consider exception handling essential; I am not arguing against it,
as such.

I consider it so essential that I've almost forgotten the above
efficiency advantage. The (1) expressiveness advantage of not cluttering
the "happy" execution path of the code with checks and (2) the
thoroughness of it (no risk of forgetting a check) overshadow the speed
advantage, but that is nice also.

I wouldn't start a new C project from scratch without implementing
exception handling.

(In fact, I developed an exception handling library in the late 1990's
which is used in Wireshark for catching truncated or otherwise malformed
packets.)

A new programming language invented today without exception handling is
too stupid for words. (And no, I don't consider option types to be a
serious contender against exception handling, because they still require
checking at every level. They just deal with the problem of forgotten
checks.) Also, in this paragraph, by "today" I actually refer to the
last 35 years.
