title: In Clojure how can I pass multiple arguments to a defmethod?
body: <p>I wish to create a multi method which I call like this:</p>
  
  <pre><code>(defmethod some-method "some value"
    [ a b ]
    b)
  </code></pre>
  
  <p>: but which selects the function based only on the first paramter 'a'. How can I do this:</p>
  
  <pre><code>(defmulti some-method
    WHAT GOES HERE?)
  </code></pre>
