As someone who does quite a bit of C++ recently: for most uses readability is king. If you did want squeeze out the extra performance you could also do something where you store `std::variant<>` inside a struct and provide an API like this: if (auto int_value = value.i()) { // *int_value == your int } and expose a `std::variant<> &variant();` for use cases where you want the more complex/faster stuff.
