The simplest way to do this:
#define PyTuple_GET_ITEM PyTuple_GetItem
This will not add new names to ABI. Such defines can be added in a separate
header file included for compatibility.
It is exactly what I am proposing :-)
But those do not have the same semantics. PyTuple_GetItem() checks its
arguments and raises an error if you pass it something else than a
tuple, or if the index is out of bounds. PyTuple_GET_ITEM(), however,
will crash if you do so.
There are no guaranties that PyTuple_GET_ITEM() will crash.
In all cases when PyTuple_GET_ITEM() is used for getting the reference
to a tuple's item it can be replaced with PyTuple_GetItem().
But if PyTuple_GET_ITEM() is used for getting a reference to a C array
of items it can't be replaced with PyTuple_GetItem(). And actually there
is no replacement for this case in the limited API.
PyObject **items = &PyTuple_GET_ITEM(tuple, 0);
