Does anyone know of an example of a non-trivial codebase written in this style?<p>How do you do this cleanly when, e.g., you need to make a network call and then based on what the result returned to you is, either do something with a local database, make a different network call, or return a result to your user. Also, error handling...<p>It seems to me like monads must be the logical conclusion to this style of programming, or else you wind up with a mess (or just abandoning this technique.)
