"Does not give" you isn't that too confusing to bring up? What if we instead show that d.filter(|s| !s.is_empty()) produces this?

Ok. I realize I'm not the target audience, I don't actually know what style works best to communicate.
I would not use this style myself -- I would not mention confusion, I would just underscore the facts as well as possible.
Just my thoughts -- it's awesome this PR addresses this in some way, by underscoring the facts of how this function works!

How about assert!(d != &["a", "b", "c"])?
