title: passing array or slice into variable args function in golang
body: <p>filepath.Join method takes in a <code>...string</code> argument but I have a <code>[]string</code> that I would like pass in.  When I attempt to do this I get the following error:</p>
  
  <pre><code>cannot use append(elems, spadePath) (type []string) as type string in argument to filepath.Join
  </code></pre>
  
  <p>Is there a way to convert between a []type and a ...type?</p>
