> Of course you can tweak things to be fast in hakell, but to be able to actually program haskell in such a way to, beat other languages in performance, is not a trivial skill. No kidding: http://benchmarksgame.alioth.debian.org/u64/program.php?test=regexdna&lang=ghc&id=2 It's mostly a matter of knowing C, then knowing how to torture GHC into doing what the C would do.

Linking to the benchmark game as if it means something should be a bannable offense. When you look at something that encourages speed at all costs, that is what you will see. People do low level optimizations like that to gain 0.5% better performance. That does not mean you need to do anything like that to get good performance.

      We can stop bothering about your -- "That does not mean you need to do anything like that to get good performance."

        You can do whatever you want. But drawing nonsense conclusions won't suddenly become reasonable just because you are defensive about the shootout.

        My conclusion is that you've made a claim and done nothing to support that claim.
