Hi there. I'm working on my first Haskell app in production; Just wondering.. Do you guys use parsec in production? What is the motivation for having Haskell to be half of the codebase? (Are there some open-source domain-specific libraries that are used intensively? Or do you guys prefer to implement things in-house (on top of libs that are more abstract)?) And if parsec is used in production, any tips on how to best design/debug parsec parsers? (Thanks!) Lastly, in your experience, what are some of the best monads / design patterns to improve team productivity? :{ Really curious about it
