This is the list of elements with indices i, start_index <= i < end_index.

The sublist is backed by the given list, which means:
|
|
- Modifications to the sublist affect the whole list.
|
|
- Modifications to the whole list are immediately visible in the sublist.
|
|
- The sublist is only valid as long as the whole list is valid.

- The sublist must not be passed to the gl_list_sortedlist_add() function.
