title: How to access global method from object?
body: <p>I have this code:</p>
  
  <pre><code>def login(user,pass)
  end
  
  class Bob
    def login(pass)
      login('bob',pass) #ERROR#
    end
  end
  
  login('hello','world')
  bob = Bob.new
  bob.login('world')
  </code></pre>
  
  <p>When I try to execute the code from the command line, I get an wrong number of Arguments error on the line I commented as <code>#ERROR#</code>.  I'm guessing this is because I'm not successfully accessing the global <code>login()</code> function instead?  How do I reference it?</p>
