Reading std::vector or most parts of the C++ standard library is the path of insanity. It puts you in touch with some fairly arcane parts of C++, and on top of that you have the allocator class, which std::vector inherits from rather than embeds because if it were embedded, it couldn’t be zero bytes (otherwise every object wouldn’t have a different address). By comparison, glibc isn’t so bad to read. Same with the standard library for Python, Go, Rust, etc… I have never had such a problem reading library source code as I have with the C++ standard library.
