There are tons of facilities in the language intended for library authors and abstractions that are absolutely intended to be used out of the box. This is just how things are, features are provided at various levels of abstractions. I know HN loves to collectively hate on C++ but “caste system?” Lol

I think "caste system" is the perfect word for it. I don't think it is a bad thing though, I am fine with having such castes in c++. First time I saw coroutines of c++ I was definitely like "yep, this is for library writers". I am not excited about it, but I am excited about libraries that will use it.

It is similar how templated code that basically becomes "magic" for an average programmer like me. I can't wrap my head around such complex templated libraries either but the simplicity of using such libraries are sure welcomed by me. I think it is perfectly have some language features for more advanced users.

Hey, at least they are adding concepts. Maybe I will move up to another caste and will be able to write more complex templated code now.

Yeah, it's part of the charm of C++. The is almost horrifyingly modifiable. As a library author, that gives a lot of control over the functionalities of the abstractions you expose.

For a day to day programmer, that sort of concern is (usually) overkill.
