  43 Another generally useful object type is an list of object pointers.
  44 This is a mutable type: the list items can be changed, and items can be
  45 added or removed.  Out-of-range indices or non-list objects are ignored.
  46
  47 *** WARNING *** PyList_SetItem does not increment the new item's reference
  48 count, but does decrement the reference count of the item it replaces,
  49 if not nil.  It does *decrement* the reference count if it is *not*
  50 inserted in the list.  Similarly, PyList_GetItem does not increment the
  51 returned item's reference count.
