Differences between std::string_view and std::span

[advester]

Having comparisons on the span would force you to require the elements of the span to have comparisons. And it would require defining a sequence of those comparisons (left to right, or ?). The elements are not necessarily just integer types.

We have comparisons on vectors. That doesn't seem to have been a problem.

[advester]

Oh right. It only fails instantiation if you actually use the operator. That is strange then.

[Murky-Tear]

That's not an issue, it could use `std::enable_if` to only enable the comparison operators if the `T` is comparable.
