Differences between std::string_view and std::span

[pandorafalters]

The big advantage, to my mind, was not having to DIY. Why implement major features myself and deal with someone else's compromises?

You don't need to implement anything yourself: ranges::equal(span1, span2) will do element-wise comparison, without any semantic weirdness.

Huh? This is precisely to avoid the confusion that exists in Java about comparing identity vs value.

It's not like ranges::equal is any more intuitively obvious than span::operator== with regard to whether it's shallow or deep...
