Using transducers is really easy and intuitive (with "comp" letting you compose a pipeline of transformations in a readable way).

Writing custom transducers, especially stateful transducers is really difficult. But that's not something you'll do often. My 10kLOC complex app has three stateful transducers that I wrote.

I think transducers are an under-appreciated aspect of Clojure. They are an extremely valuable and flexible tool, and have allowed me to write reusable and composable code and tackle significant complexity, all with great performance.

Yes I agree with you that transducers are OK. I think that they miss a bit in ergonomics, not power.
