5 Another generally useful object type is a list of object pointers.
6 This is a mutable type: the list items can be changed, and items can be
7 added or removed. Out-of-range indices or non-list objects are ignored.
8
9 *** WARNING *** PyList_SetItem does not increment the new item's reference
10 count, but does decrement the reference count of the item it replaces,
11 if not nil. It does *decrement* the reference count if it is *not*
12 inserted in the list. Similarly, PyList_GetItem does not increment the
13 returned item's reference count.
