title: How to access private methods
body: <p>My understanding is that <code>private</code> means being private to an instance. Private methods can't be called with an explicit receiver, even <code>self</code>. To call a private method, I have to go through a process like below:</p>
  
  <pre><code>class Sample
    def foo
      baz
    end
  
    private
    def baz
  
    end
   end 
  
  Sample.new.foo
  </code></pre>
  
  <p>This will call the private <code>baz</code> method. Is there a way to directly call a private method with an explicit receiver?</p>
