This could also be moved into check_pow_args (or rather unpack_pow_args).
BTW, it is still a question whether __rpow__ and __ipow__ should support the third argument. Normally they never called with three arguments. So it may be better to leave the current PR code, it will be easier to change in future.

Yes, we can open a new issue about that. For now, we only change the error message, not any logical parts. Thanks a lot for the review! 👍

The second option was to convert these functions to use
check_num_args(args, ...), but this feels like a simplier solution.After:
