Which raises the problem that it works globally, unlike the unix uniq
which only uniqs consecutive elements. Passing in a block would lead to
a performance hit since you'd need to compare every pair of elements
without the benefit of a hash function. A uniq_by would probably cover
most of the use cases anyway.
