Save yourself the trouble and just fork and maintain https://github.com/tcbrindle/span . It's already released under BSL-1.0, so no problems there either. Then there's another one, https://github.com/martinmoene/span-lite, equally BSL-1.0. It appears std::mdspan is slightly more of a challenge.

+1. They're Boost licensed, and Boost friendly authors to boot.

thank you for the pointers. I will check their implementations. Do you know why were these not proposed/accepted for inclusion in Boost?

I personally use span-lite. It works well on C++ 98, incidentally.

In C++ 98 and without decltype and declval, it is more difficult to restrict the overloads of the templated constructors of span, I have to see how they do that.

In any case, implementation is easy, it'll be the documentation which is hard, as always.

For a clone of std::span, one can base the documentation on cppreference.com, which is better than developing from scratch. Best regards, Hans
