.. warning::
The function is marked as unstable because the final mechanism
for reserving extra data after an instance is not yet decided.
Once :pep:`697` is implemented, the mechanism described there can
be used to reserve the extra data.
For allocating a variable number of fields, prefer using
:c:type:`PyVarObject` and :c:member:`~PyTypeObject.tp_itemsize`
instead.
