title: converting list of type Integer to list of type Int
body: <p>i'm trying to convert this list [1..20] from [Integer] to [Int]</p>
  
  <pre><code>map fromInteger [1..20]
  </code></pre>
  
  <p>however this still gives me a list of Integers</p>
  
  <p>This on its own converts 2 which is Integer type to Int
      fromInteger 2 :: Int</p>
  
  <p>What's wrong</p>
