That just adds to the incoherency.

It's why I've found Rust a joy - enough had happened in programming languages, that it was able to reinvent C++ with some of the best parts of the Haskell/ML/Scala family, some of the ergonomics of Python/nodejs, and bringing the borrow checker too.

C++ is this weird amalgam of like 7 different generations of languages.

But by far the worst part is the developer hostility behind the idea of UB. "Oh, this is not an error, it will compile, we will just secretly stab you in the back."

You can get good and avoid it, and there are tools to help you, but why is that at all a reasonable stance for the definition of a language?
