Eep. No. At least, not in anything public. Universal impl trait arguments can't be turbofished, so you're placing an unnecessary constraint on your caller.

As I understand it &impl Meower also uses dynamic dispatch, whereas the generic version will generate a specialized version for each concrete type it is called with.
