 let me have another look, can you rebase Rebased+green Hello @jbrockmendel! Thanks for updating the PR.

 - There are no PEP8 issues in the file [`pandas/core/ops.py`](https://github.com/jbrockmendel/pandas/blob/5f484822e32cfb3af8c89cbe307680f419c06142/pandas/core/ops.py) !

 - There are no PEP8 issues in the file [`pandas/tests/series/test_operators.py`](https://github.com/jbrockmendel/pandas/blob/5f484822e32cfb3af8c89cbe307680f419c06142/pandas/tests/series/test_operators.py) !

 doesn't this overlap with #22293 ? Yep, commented to that effect over there. ok then, merge that one first? >ok then, merge that one first?
