There could be a situation where it doesn't matter which key do you get,
as soon as you have one of them. For example, you have array of "news
headline" => "date" and you want to display one headline for each date.
Key-preserving unique function would serve you very good - as long as you
don't care which one you are displaying (and if you are displaying just
one, you don't care anyway).
