Template std.algorithm.sorting.multiSort
void
multiSort(Range)(Range r)
if (validPredicates!(ElementType!Range, less));
Sorts a range by multiple keys. The call multiSort!("a.id < b.id",
"a.date > b.date")(r)r by id ascending,
and sorts elements that have the same id by date
descending. Such a call is equivalent to sort!"a.id != b.id ? a.id
< b.id : a.date > b.date"(r)multiSort
Arguments
template multiSort(less...);

auto pts2 = [ Point(0, 0), Point(0, 1), Point(0, 2), Point(5, 5) ];
multiSort!("a.x < b.x", "a.y < b.y", SwapStrategy.unstable)(pts1);
assert(pts1 == pts2);
