Abstract:
We propose the following change to the C++ Working Paper. If an
mdspanobjectxhas noncomplexvalue_type, and if thatmdspandoes not already have accessor typeconjugated_accessor<A>for some nested accessor typeA, then we propose to changeconjugated(x)just to returnx. Delaying this until after C++26 would be a breaking change.I submitted this today (2024/04/08) as P3050R1.
This supersedes PR #437 , which I created in November 2023, and which still hasn't been merged.
