So span<void const> then or as that isn't accepted span<char const> assuming sizeof(char)==sizeof(byte)

span<void const> doesn't exist, though. I was giving it as an example of something that I would have added to the hypothetical hash2::span, but no existing span library has it. If we limit ourselves to std::span, I suppose we can just add three (or four) overloads, one per byte type. (Four because of char8_t.) Definitely something to consider when Boost drops support for C++17. Should be any time now.
