Rich Hickey has just released yet another new library for Clojure: Reducers. It provides optimised, parallel functions that operate on collections, as opposed to the existing functions in core that are optimised for laziness and operate on sequences.

Rich Hickey has just released yet another new library for Clojure: Reducers. It provides optimised, parallel functions that operate on collections, as opposed to the existing functions in core that are optimised for laziness and operate on sequences.

There's a great introductory post by Rich himself on the Clojure blog:

Clojure/core - Reducers - A Library and Model for Collection Processing

I'm happy to have pushed today the beginnings of a new Clojure library for higher-order manipulation of collections, based upon reduce and fold. Of course, Clojure already has Lisp's reduce, which corresponds to the traditional foldl of functional programming. reduce is based upon sequences, as are many of the core functions of Clojure, like map, filter etc.
