 synopsis:       Parser combinators with fast-path and slower fallback for error reporting
 description:    PariPari offers two parsing strategies. There is a fast Acceptor and a slower Reporter which are evaluated in parallel. If the Acceptor fails, the Reporter returns a report about the parsing errors. Like Attoparsec, the parser combinators backtrack by default.
