/* List object interface

Another generally useful object type is a 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: PyList_SetItem 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, PyList_GetItem does not increment the returned item's reference
   count.
