title: What does "..." mean when next to a parameter in a go function declaration?
body: <p>I was going through some code written in Google's Go language, and I came across this:</p>
  
  <pre><code>func Statusln(a ...interface{})
  func Statusf(format string, a ...interface{})
  </code></pre>
  
  <p>I don't understand what the <code>...</code> means. Does anybody know?</p>
