There's several typdefs of std::basic_string we do not support yet:

std::u8string (C++20)
std::u16string (C++11)
std::u32string (C++11)
std::pmr::string (C++17)
std::pmr::wstring (C++17)
std::pmr::u8string (C++20)
std::pmr::u16string (C++17)
std::pmr::u32string (C++17)

See https://en.cppreference.com/w/cpp/string/basic_string

We are also missing cbegin(), cend(), rbegin(), rend(), crbegin(), crend() and the map and set containers. Probably just the tip of the iceberg 🗻.

Definitely. Maybe this could be part of the container interface somehow?

Yes, it would make much more sense to base it on Named Requirements. That might be quite an undertaking though.
