Parsec is designed from scratch as an industrial-strength parser library. It is simple, safe, well documented (on the package homepage), has extensive libraries and good error messages, and is also fast. It is defined as a monad transformer that can be stacked on arbitrary monads, and it is also parametric in the input stream type.
