title: Is it possible to build a Restful API in Haskell without using Reader/Writer/State Monad or Monad Transformer
body: <p>As a beginner, I feel Reader/Write/State Monad is difficult to understand. And Monad Transformers is even more difficult. I don't see the usage of them in other languages, which makes me a bit hard to relate them to my existing web development experience. </p>
  
  <p>Is it possible to build a Restful API that talks to Postgres in beginner-friendly Haskell? Meaning without using this advanced stuff like Monads/Monad Transformers. </p>
