About the forward:
```
template <typename R1, typename R2, typename Compare>
bool includes(R1 &&Range1, R2 &&Range2, Compare C) {
  assert(is_sorted(Range1, C) && "Range1 must be sorted with respect to C");
  assert(is_sorted(Range2, C) && "Range2 must be sorted with respect to C");
  return std::includes(adl_begin(Range1), adl_end(Range1), adl_begin(Range2),
                       adl_end(Range2), std::forward<Compare>(C));
}
```
I just have a question that why other places no need to forward `C`?
