>I believe one of the arguments was also that these couldn't be written in statically typed languages. Although, I do not know if this turned out to be true.
It's not true, they were just abstrusely defined and there's some weirdness around the implicit effects that you can choose to either ignore or incorporate into the equivalent.
Fusion is one of the main things Haskell is known for and an API that gets close enough to what one would use transducers for is `Control.Lens.Fold`.

Others have made more faithful attempts at making it explicit, such as in this post: http://jspha.com/posts/typing-transducers/
