std.variant is so incredibly slow! It's practically unusable for anything, which requires even a tiny bit of performance.
You do realize you actually benchmark against a function that does nothing, right? Clearly there are ways in which we can improve std.variant to the point initialization costs assignment of two words, but this benchmark doesn't help. (Incidentally I just prepared a class at C++ and Beyond on benchmarking, and this benchmark makes a lot of the mistakes described therein...)
