Instead of copying a list, sorting it just to check it's sorted, and making a QSet out of it just to check the size is the same as that of the list (thereby checking there were no duplicates), simply apply adjacent_find with greater_equal. If none of the elements is ≥ their successor, that means all elements are < their successor, and _that_ means the range is sorted and has no duplicates. q.e.d.
