I liked the article (in fact for me it was a better introduction that the "Liberating Programming, Period" article by Weizmann), but Hacker News is kind of a lost cause regarding, well, "news". Everything that cannot be shoehorned into their view of faux-FP has to be bad.

Someone should probably post this on lobste.rs, which is a bit more open minded (I would, but don't have an account).
