There are few callers of nb_inplace_power at all (AFAICT, only PyNumber_InPlacePower); in turn, PyNumber_InPlacePower is called with the implicit Py_None always: - ceval.c, for INPLACE_POWER (which is binary) - operator.ipow (which is also binary) - class.c, from bin_inplace_power, which in turn is called from instance_ipow if the instance's 3rd argument to nb_inplace_power is Py_None (if there is a non-None third argument, instance_ipow invokes __ipow__ with three arguments if __ipow__ is defined, else it invokes __pow__ with three arguments) The only case I could find where a third argument is non-None is when the builtin pow() is invoked, which then invokes nb_power (but not nb_inplace_power) with three arguments.
