/*

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 as 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.
