A blurb I just wrote about Clojure.

Clojure is a language that employs a simple syntax to manipulate data types and structures that are as far from the constraints and limitation of the computer hardware as possible. The simplicity of the syntax allows rich and complex data manipulations to be accomplished with very little code — vastly increasing programmer productivity over languages that employ an elaborate syntax to manipulate data that hews close to the machine architecture. For any problem in which the richness and complexity of the data manipulations outweighs the possible efficiencies of adherence to physical hardware, it is difficult to imagine a better and more productive language than Clojure.
