Hello Edgar Does the interpreter fail actually fail on particular input rather than by it running to long? Tail recursion isn't very important for Haskell as it is a lazy language, however for any Parsec parser avoiding _left recursion_ is crucially important as it is a LL recursive descent parser. Also how are you running the program - GHCi, Hugs? The import declarations for Parsec suggest that you are using a old version. Best wishes Stephen
