Description

What is the status of C-style array syntax for extents T[M][N] for mdspan?
Is it still 'preferred'?

At some point around r5 of P0009 this 'preferred' natural syntax for extents was bumped to an appendix and to P0332 for proposals to relax language constraints on incomplete bounds. Then, for the last few revisions, I don't see a reference.

Thanks for any pointers - forum discussions or elsewhere in github issues perhaps.
