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.

It seems counterintuitive, but composing transducers yields a reducing function that runs the transformation steps left->right. What you are composing is the reducing function transformations (right to left, ordinary composition), but their result, having been built inside-out, runs the steps outside-in. So (comp tx1 tx2...) runs in same order as (->> xs tx1 tx2...)
