It’s funny because you really have to have a lot of experience with the language to articulate these issues. C++ is the worst language, besides all the other ones, when it comes down to performance and third party library availability.

I’ll just throw in my own pet peeves here.

The existence of .h files is still a big problem. I’m not aware of another language (besides c of course) that basically forces you to type the same letters twice in slightly different ways in order to expose a public api.

I also don’t understand why there’s still no way to print an enum value.

However there is some progress. I think std::span fixes the issue with the vector of const vs const vector. The Eigen library gives a (not perfect, but very convenient) matrix type. And I think I heard something about modules?

> The existence of .h files

C or C++ don't specify or require .h files. The languages don't even specify any file extension.

What C and C++ specify is the concepts of declaration and definition, and require only one definition across all translation units. Thus it's customary to simply have a single source for declarations to ensure they all stay consistent in spite of their usages, and those declarations are used once by wrapping them in include guards.
