--- Comment #5 from Desmond Gold <cooky.ykooc922 at gmail dot com> --- when I mentioned being "inspired by," I was referring to drawing guidance from existing reference implementations like libc++, STL, and Kokkos for the <mdspan> implementation in libstdc++. Specifically, for how they implement the preconditions and layout_stride. I apologize for not explicitly defining what I meant by "inspiration" earlier. However, it's important to note that my work primarily adheres to the standards' definitions rather than directly replicating code. This approach ensures alignment with the intended functionality while respecting authorship, copyright, and licensing concerns. >From the link you've checked out, you'll notice the implementation is still a work in progress. It's incomplete and would greatly benefit from additional feedback to incorporate the missing elements :>
