What's the point you might ask? We might have changed an object without it's key changing. In which case this lookup makes sense.

mapUniqSet :: Uniquable b => (a -> b) -> UniqSet a -> UniqSet b #

unsafeUFMToUniqSet :: UniqFM a a -> UniqSet a #

`unsafeUFMToUniqSet` converts a ``UniqFM` a` into a ``UniqSet` a` assuming, without checking, that it maps each `Unique` to a value that has that `Unique`. See Note [UniqSet invariant].
