title: How to pass a symbol as a keyword argument?
body: <p>I export a few symbols from a package and use them internally in a case statement.  I'd like to pass one of the symbols (e.g. medium-size) as a keyword argument to a generic method, like this:</p>
  
  <pre><code>(solve problem :optimize-for :medium-size :another-keyword t)
  </code></pre>
  
  <p>but this gives an "odd number of &amp;KEY arguments" error.  Am I misunderstanding something fundamental about symbols or keyword arguments?</p>
