title: Do you think functional language is good for applications that have a lot of business rules but very few computation?
body: <p>I am convinced that functional programming is an excellent choice when it comes to applications that require a lot of computation (data mining, AI, nlp etc). </p>
  
  <p>Is functional programming being used in any well known enterprise applications or open source projects? How did they incorporate business logic into the functional design? </p>
  
  <p>Please disregard the fact that there are very few people using functional programming and that it's kind of tough.</p>
  
  <p>Thanks</p>
