Hello, My name is Xing GUO. Maybe it is a little bit late to ask something about GSoC, I am interested in implement YAML library... I am not a proficient Haskeller, but, I think I could do it perfectly ... What I have done in Haskell is a toy regex engine https://github.com/higuoxing/Haskell-Re ... Could this be a competancy test ? It will be very appreciated if someone could help me ... Regards, Xing
