Clojure transducers

[Puming via Digitalmars-d]

Clojure is introducing a new way of composing functions (reducers 
this time), called transducers. It looks similar to 
composition/binding of functions, but somehow different. My 
functional-fu is not that deep to understand the statement 
"transducers are as fundamental as function composition" but it 
seems quite interesting. What is D's attitude toward this concept?

Here is a blog I read about transducers today:
