A Rebuttle of the C++ FQA
- AnimalMuppet 11y agoNicely done! Some comments: > all popular languages have context-free (or “nearly” context-free) grammars, while C++ has undecidable grammar The article quotes the FQA as saying that. Notice how this neatly defines C++ as "not a popular language", against all evidence of real-world use. > Yossi also echoes the claim that adding exception handling always adds a runtime cost even when no exception is thrown. This is no longer true. Was it ever? I thought that the idea of exceptions in C++ was always "no cost if not thrown". > Manual memory management should not be used. Well, it shouldn't be used except to build abstractions that insulate you from manual memory management.
- corysama 11y ago> Was it ever? I thought that the idea of exceptions in C++ was always "no cost if not thrown". Long, long ago enabling exceptions would add some overhead to all functions. When "zero cost exceptions" went mainstream it was a bit of a big deal, but a lot of people didn't read the memo and still argue about their cost. Either way, I'm not a fan of exceptions in any language. I'd prefer an Either<Result, Error> return value any day.
