title: Haskell in Excel
body: <p>I've seen a couple of sources casually refer to the idea of <em>"Haskell in an Excel spreadsheet"</em> - as if this is something that everybody is familiar with and knows about.</p>
  
  <p>This is certainly news to me. The <em>idea</em> has obvious appeal - Haskell would be ideally suited to this kind of thing. But has anybody ever actually got this to work?</p>
