- Another generally useful object type is an tuple of object pointers.
- This is a mutable type: the tuple items can be changed (but not their
- number). Out-of-range indices or non-tuple objects are ignored.

- *** 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.
