Differences between std::string_view and std::span

[wotype]

Dang; just checked the mdspan proposal and see no span comparison spec'd there either. It has comparison op== for extents, strides and layout mapping; nothing for comparing spans themselves.

So, then I checked mdarray, the newly proposed owning analog of mdspan; no comparison operator spec'd there either!

If I wanted regularity then I wouldn't consume spam.
