- Another generally useful object type is an list of object pointers.
- This is a mutable type: the list items can be changed, and items can be
- added or removed. Out-of-range indices or non-list objects are ignored.
-
- *** WARNING *** setlistitem does not increment the new item's reference
- count, but does decrement the reference count of the item it replaces,
- if not nil. It does *decrement* the reference count if it is *not*
- inserted in the list. Similarly, getlistitem does not increment the
- returned item's reference count.
