title: Atom is not highlighting Haskell syntax?
body: <p>I am using Haskell in Atom text editor <code>version 1.23.1</code> on Mac. Other languages syntax is highlighted correctly but when I code in Haskell the text editor does not highlight the syntax correctly and shows it as plain text. I have tried searching for it and found that in Atom pressing <strong><em><code>ctrl-shift-L</code></em></strong> I can temporarily change the grammar. However, there is no option for Haskell as can be seen in the screenshot below. </p>

  <p>The screenshot below shows what I am expecting. </p>

  <p>Is there anything that I might have done wrong? Can anyone give me a clear and easy solution to this problem. Thank you</p>
