  > I literally have never found a place where `std::variant` has any positives that can't be written a different, clearer way with drastically better compile time and run time performance. So, don't use std::variant? To produce performant output from a C++ compiler, you have to make the same sort of informed decisions that you would if you were writing assembler. Possibly not using the standard library at all.
