This returns 16:

(reduce (fn [acc x]
          (let [x' (* x x)]
            (if (> x' 10)
              (reduced x')
              x')))
        (range))

But replacing `reduce with `reductions will never terminate:

(reductions (fn [acc x]
              (let [x' (* x x)]
                (if (> x' 10)
                  (reduced x')
                  x')))
            (range))

This is because `reductions ignores 'clojure.lang.Reduced, it never tests for `reduced?

I know that I only just discovered the `reduced, function, but `reductions is a big part of my debugging process, so it's unfortunate that they don't work together.
