Hi @jbrockmendel , |

Please use your best judgement. |

Okay, thanks.. I’ll update the tests to keep things consistent and aligned with user expectations. |

Outdated

why is a new keyword getting added?

i see, you're trying to avoid changing any old behavior. in this case, the new behavior should be generally better than the old behavior. if you find cases where it isn't, those likely represent bugs in _cast_pointwise_result.

while trying to put the _casr_pointwise_result in map and updating the test cases, like you mentioned, I faced some bugs. It was not fully implemented for some particular niche types. (truediv , rtruediv or ns, ms ) and while I don't remember all the types.. this function definitely needs few more updates...

we don't want this new keyword.

as the current implementation is not working for all the types, do you have a suggestion on how I should approach this without introducing the new keyword?

pls avoid unrelated changes

Sorry, but due to a ci check on formatting, I used ruff and it changed few files. Thanks for pointing out, I will revert it back.
