+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.
