25.7.29.1 Overview [range.chunk.overview]
chunk_view takes a view and a number N and produces a range of views that are N-sized non-overlapping successive chunks of the elements of the original view, in order.
The last view in the range can have fewer than N elements.
The name views::chunk denotes a range adaptor object ([range.adaptor.object]).
Given subexpressions E and N, the expression views::chunk(E, N) is expression-equivalent tochunk_view(E, N).
[Example 1: vector v = {1, 2, 3, 4, 5};
for (auto r : v | views::chunk(2)) { cout << '['; auto sep = ""; for (auto i : r) { cout << sep << i; sep = ", "; } cout << "] ";}// The above prints [1, 2] [3, 4] [5] â end example]
