+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.

+count, but does decrement the reference count of the item it replaces,

+inserted in the tuple.  Similarly, PyTuple_GetItem does not increment the
+returned item's reference count.
