Performance boost in Clojure 1.3 (alpha4)

While I don't doubt Clojure 1.3 can get similar performance to Java, that's not what this benchmark shows. The Java and Clojure functions he's comparing don't even take and return the same argument types. He's comparing boxed Integers to primitive longs.<p>In the comments he says he saw no difference between Integer and ints. When I ran Tak.java with longs like the Clojure code my time went from 13s to 8s.

Clojure is a language that has been teaching me a lot about different avenues of programming I hadn't previously encountered. I know many of them aren't new, but they are new to me and yet still approachable.<p>I really like the type-hinting approach; more detail and performance if you want or need, but otherwise don't bother. I guess it still doesn't have the type-safety of a static language, but now it has the performance.

Im really happy about what new clojure versions bring! Rich sayd this primitiv stuff in 1.3 is the second step to what the want to end up with.<p>Look at: <a href="http://www.infoq.com/interviews/hickey-clojure-protocols" rel="nofollow">http://www.infoq.com/interviews/hickey-clojure-protocols</a>

I would like a way to de-italicise all the text on a page because I find it much harder to read.<p>This is the second HN link so afflicted today. <a href="http://news.ycombinator.com/item?id=2132591" rel="nofollow">http://news.ycombinator.com/item?id=2132591</a>
