title: How should I debug a "symbol X does not fit here" error when using c2hs?
body: <p>I'm new to using c2hs and having <a href="https://github.com/jspahrsummers/Arbiter/pull/66#issuecomment-247859427" rel="nofollow">this issue</a>.</p>
  
  <p>I'm not sure how to start debugging this, and haven't found anything with a Google search or by looking through the issues on GitHub.</p>
  
  <p>Where should I begin, and what are some resources that could help?</p>
  
  <p>Thanks in advance.</p>
