I think it's worth pointing out though that idiomatic C is probably going to be more consistently performant. It seems common to run in to situations in Haskell where one change can cause 10X speedup, but I don't see that nearly as often with C code. I don't have a lot of evidence on hand to support this, just what I've observed personally. This seen fair? Relevant?
