25.6.3.1 Overview [range.single.overview]
single_view produces a view that contains exactly one element of a specified value.
The name views::single denotes a customization point object ([customization.point.object]).
Given a subexpression E, the expressionviews::single(E) is expression-equivalent tosingle_view<decay_t<decltype((E))>>(E).
[Example 1: for (int i : views::single(4)) cout << i; // prints 4 â end example]
