US246 22.07.3 [views.span] span should be constructible from a contiguous range P1394 #242
Description
Span should be constructible from a contiguous forwarding range or iterators thereof, and not just "Container" types with a data() member function. As this has the possibility of affecting overload resolution and SFINAE, it may not be possible to repair std::span in a later standard.
Proposed change:
Apply P1394
