What about straight C??? There are many great stats libraries in C (e.g. Apophenia). C is not a hipster language but maybe (like polaroid filters in Instagram) it's time for it to make a "retro" comeback. C kicks ass for speed. Obviously.

I'm waiting for somebody to make a CoffeeScript for C. No semicolons, comprehensions, syntactic sugar for function pointers, etc.
