title: tuple or data for loading file haskell
body: <p>I have to load a database of the format:</p>
  
  <pre><code>"Blade Runner"
  "Ridley Scott"
  1982
  ("Amy",5), ("Bill",8), ("Ian",7), ("Kevin",9), ("Emma",4), ("Sam",7), ("Megan",4)
  </code></pre>
  
  <p>into </p>
  
  <pre><code>type Rating = (String, Int)
  data Film = Film {  title :: String,
                      director :: String,
                      year :: Int,
                      ratings :: [Rating] } deriving (Read,Show)
  </code></pre>
  
  <p>Would it better to leave Rating as a tuple or change to a data type?
  As I will have to save the file as well.</p>
