+\tcode{chunk_by_view} takes a \libconcept{view} and a predicate, and

+The name \tcode{views::chunk_by} denotes
+a range adaptor object\iref{range.adaptor.object}.
+Given subexpressions \tcode{E} and \tcode{F},
+the expression \tcode{views::chunk_by(E, F)} is expression-equivalent to
+\tcode{chunk_by_view(E, F)}.
+\begin{example}
+\begin{codeblock}
+vector v = {1, 2, 2, 3, 0, 4, 5, 2};
+
+for (auto r : v | views::chunk_by(ranges::less_equal{})) {

+  for(auto i : r) {
+    cout << sep << i;
+    sep = ", ";
+  }
+  cout << "] ";
+}
+\end{codeblock}
+The above prints: \tcode{[1, 2, 2, 3] [0, 4, 5] [2]}
