cas? Maybe choose a different name 😅

I considered something like xchg but that would imply the target is overwritten if it exists. I'm happy to use a different name but I don't have ideas for anything better.

I feel like that name is a bit too close to just 'putting the code entirely in the name' but when I don't feel strongly about things and someone felt strongly enough about it to make a comment, I'm going to apply the suggestion.

How about rename_or_delete? The 'to' part is already implied by the rename, and avoids 'delete if exists' sounding like 'delete the target if it exists'. This way, one of those two verbs are clearly happening to the same subject (the source); we either rename the thing, or if we can't, we delete it.
