Nope, that's the funny feature of transducers. Like lenses in Haskell, transducers compose in reversed order.

    (sequence (comp (map inc) (filter even?)) (range 10))
    ;;=> (2 4 6 8 10)
    (->> (range 10) (map inc) (filter even?))
    ;;=> (2 4 6 8 10)

Both test functions in transduce-bench return 250000500000.
