  /* List object interface */
  
  /*
  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 *** 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.
