+\tcode{cache_latest_view} caches the last-accessed element of
+its underlying sequence

+\begin{note}
+This is useful if computation of the element to produce is expensive.

+The name \tcode{views::cache_latest} denotes
+a range adaptor object\iref{range.adaptor.object}.
+Let \tcode{E} be an expression.
+The expression \tcode{views::cache_latest(E)} is expression-equivalent to
+\tcode{cache_latest_view(E)}.
