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

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.

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