Summary

During review of mdspan, Library suggested that we should rename pointer, data, and contiguous, as the use of these names overloads some existing meanings in the Standard Library and may lead to confusion. The authors investigated alternative names, and proposed them in this paper. Library Evolution was in favor of making the name changes.

Next Steps

Take an electronic poll to confirm sending P2604R0 (mdspan: rename pointer, data, and contiguous) to Library for C++23 classified as B2 - Improvement.
