Voted C, C++ & Haskell, but other languages are also nice. C is pleasant for its simplicity and straightforwardness. C++ is huge and complex, and I’ve never believed in OOP, but I know of no better language for generic programming. Haskell, on the other hand, is rather small and pretty. It doesn’t get in your way, it informs your writing in other languages, and its type system makes the angels weep.
