K as a Prototyping Language

Last year someone benchmarked a simplified raytracer in a few different languages--primarily to show off OCaml. Later, someone wrote the raytracer in 7 lines of K. <a href="http://www.nsl.com/k/ray/ray.k" rel="nofollow">http://www.nsl.com/k/ray/ray.k</a>. The original comparison: <a href="http://www.ffconsultancy.com/languages/ray_tracer/index.html" rel="nofollow">http://www.ffconsultancy.com/languages/ray_tracer/index.html</a>

/ Right to left precedence:<p>3*2+5 / yields 21<p>Why should I learn this language that I've never heard of if it can't even do math in any sensible way? Not left-to-right, not order of operations, not lisp-like prefix. Who thought that was a good idea?

If anyone is interested in some examples, take a look at projecteuler.net - it's a series of mathematical/programming puzzles.<p>After you solve a particular problem you gain access to a forum where people detail their solution. A good amount of the solutions tend to be written in these APL languages (J, K) and may serve as a nice way to learn.

Very interesting, thanks for posting the link.<p>I'm also interested in what industries this language perfoms well.

Is it "K" or "Q" language?
