I have a few years of experiene with Haskell, and recently started Nimrod. It's an imperative language, so the differences are huge of course. I'm more productive in Nimrod. The syntax is great, similar to Python. Nimrod compiles to C without external dependencies, which makes it easy to deploy and easy to bind C libraries. Nimrod's metaprogramming is definitely worth checking out too.

And a functional version in Nimrod: https://gist.github.com/def-/ccef8bb54170b639c497

As some people noticed this was broken. Fixed version is not quite as fast, but still faster than functional C++:

  Goats Wolves Lions    C++11  Nimrod
     17     55     6     0.00    0.03
    117    155   106     0.17    0.13
    217    255   206     0.75    0.62
    317    355   306     2.16    1.89
    417    455   406     5.28    4.34
    517    555   506    10.75    8.42
    617    655   606    19.15   14.45
    717    755   706    31.58   23.04
    817    855   806    46.52   33.69
    917    955   906    67.94   48.57
   1017   1055  1006    93.75   65.25
   2017   2055  2006   731.42  500.95

I was curious how a non-functional version would fare, so I wrote one in Nimrod and it's a lot faster than the functional C++: https://gist.github.com/def-/8187448ea7a5c8da8265

Argh, someone beat us to it. We have a massive-multiplayer tournament planned for Saturday: http://ddnet.tw/#news
