##### Comment last updated on June 18, 2018 at 19:04 Hours UTC Hmm well it looks like this is going to conflict with the work being done in #21504. @ocefpaf can you see if your PR accounts for this issue (adding a test case, accordingly)? If so would be easier just to bundle this in with your change My guess is that https://github.com/pandas-dev/pandas/pull/21504 could supersede this one. I'll add tests soon. I have a limited time I can work on this. (And I'm waiting for the docstrings questions I asked there before continuing :smile:). Closing in favor of #21504
