Dear Ruby Lang developers.

I would like to ask about why the following code can work? 

Or is it a valid scenario and "as expected" behavior to ignore public call on a protected method. 

Thank you guys for the brilliant!


<pre><code class="ruby">

class A

  class << self

    def inherited(klass)
      p klass.protected_method_call
    end

    protected
    def protected_method_call
      self.to_s
    end
  end

end


class B < A

end

# output: "B"

</code></pre>
