/* Tuple object interface */
Another generally useful object type is a tuple of object pointers.
For Python, this is an immutable type. C code can change the tuple items
(but not their number), and even use tuples are general-purpose arrays of
object references, but in general only brand new tuples should be mutated,
not ones that might already have been exposed to Python code.
*** WARNING *** PyTuple_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 tuple. Similarly, PyTuple_GetItem does not increment the
returned item's reference count.
/* ob_item contains space for 'ob_size' elements.
* Items must normally not be NULL, except during construction when
* the tuple is not yet visible outside the function that builds it.
