Maybe like:
```
template <typename R1, typename R2> bool includes(R1 &&Range1, R2 &&Range2) {
#ifndef NDEBUG
  assert(is_sorted(Range1) && "Range1 must be sorted in non-descending order");
  assert(is_sorted(Range2) && "Range2 must be sorted in non-descending order");
#endif
  return std::includes(adl_begin(Range1), adl_end(Range1), adl_begin(Range2),
                       adl_end(Range2));
}
```
But it seems weird.
