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.
