Subject: Re: [isocpp-ext] P2320: "The Syntax of Static Reflection" feedback request

I've written plenty of multidimensional array slices in Matlab, Python,
and Fortran >= 90, but I don't feel like I miss the colon operator when
I use mdspan.  It's easy to mess up the indexing (especially the
three-argument version), so a tiny bit more verbosity helps me slow down
and think.
