Writing clear, concise, and efficient code in C++ has never been simpler or easier. The improvements in C++ over the last 15 years have been qualitative.
So many complex, esoteric, and difficult to maintain incantations that used to be required for efficient code generation are no longer necessary.
How do you process read-only mmaped data in C++, in accordance with the language rules? As an example.
I think there are lots of Unix APIs that are impossible to use without UB, e.g. SCM_RIGHTS (maybe io_uring as well?).
