I was torn between those two formulations, but decided on the reduce because the academic purity of an implicit hylomorphism ;) However, your formulation is more idiomatic of a lispy solution.

I totally agree that lisp isn't magic once you have seen past the alien notation and a couple of new paradigms (pervasive meta programming, fp, symbolic manipulation, laziness). But I consider it foolish to discount that barrier for a progr

"...For the last time LISP IS NOT MAGIC..." Clarke's Law, "Any sufficiently advanced technology is indistinguishable from magic". If you are used to java, clojure - or any lisp - is sufficiently advanced to be considered magic. Edit: posses

The top level index is a clojure map (a persistent hash-map by default i believe) of strings (stems) to another map of key to weighting. The hash-map is implemented as a Bagwell Trie under the hood. Check out http://blog.higher-order.net/2

This also means that you can write web apps in Clojure and deploy them on one of the many Java-based web platforms - that is, its reasonably easy to get your Clojure (or rather, JVM) based web app out there. Including App Engine (and thus

No, you just need to be willing to learn some java APIs (honestly though, not that hard. mostly they are larger, more long-winded versions of things you are used to in python). In particular for web stuff you could probably exist within the

I also came from Python (and c#/java, c, js) and have dabbled with Haskell and Clojure a bit, with a tiny bit in scheme. I personally think that learning both Haskell and Clojure concurrently has a lot of merit. Clojure is more pragmattic;
