Just a suggestion, maybe include magic_enum.h?

[WarlockD]

Wrote a simple do_repr

template<typename T>
concept onlyScopedEnums = std::is_scoped_enum_v<T>;

template<onlyScopedEnums E>
inline void do_repr(auto out, const E* self) noexcept {
    static constexpr auto type_name = magic_enum::enum_type_name<E>();
    out.type(type_name);
    if (self) {
        auto enum_value = magic_enum::enum_name(*self);
        out.value(enum_value);
    }
}

Haven't had any problems with it. I would suggest just building it into repr but it uses some hacks with with PRETTY_FUNCTION/FUNCSIG and a constexpr table to look up strings so not sure if its in scope of this project.
