Consider using for, and returning the new set of values (for [[a b] (partition 2 1 coll)] (if (= (:foo a) (:foo b)) (dissoc a :foo) a))
Here I use partition so that each item can be compared to the one that follows it. You would likely want a final step that tacks on the last item in the input coll (since it is not processed by this code).
