Sure, but how would I have known to treat string_view as a primitive?

+@jwnimmer-tri for platform review, eventually.

It would be worth updating the guide text to remove all doubt (ditto for std::span), but the ways you could have known are:

(1) Seeing it discussed in prior reviews.
(2) Recognizing that string_view is a simple pair of words (char* and size_t).
