25.7.14.1 Overview [range.join.overview]
join_view flattens a view of ranges into a view.
The name views::join denotes a range adaptor object ([range.adaptor.object]).
Given a subexpression E, the expressionviews::join(E) is expression-equivalent tojoin_view<views::all_t<decltype((E))>>{E}.
[Example 1: vector ss{"hello", " ", "world", "!"};for (char ch : ss | views::join) cout << ch; // prints hello world! â end example]
