Don't declare private function on top of class

I find that some people are declaring private function at the top of class, like this

class SomeClass

  private
  
  def private_function
    # some stuff
  end 
  
  def public_function
    # some stuff
  end
  
end

Well, if you do like that then the public_function defined below the private key word is also a private! Duh!!.

A remedy would be to do something like this

class SomeClass

  private
  
  def private_function
    # some stuff
  end 
  
  public 
  
  def public_function
    # some stuff
  end
  
end

That is as soon a private function(s) definition(s) ends you can call public thus making all functions that follow it public. But, though it’s right, it would be better to design an class like this

class ClassHowFunctionsCouldBePlaced
  
  # put all public functions here
  
  def public_function
  end
   
  protected
   
  # put all protected functions here
  
  def protected_function
  end
  
  
  private
  
  # put all private functions here
  
  def private_function
  end
   
end

If you put functions as class ClassHowFunctionsCouldBePlaced is defined, then you will have no access problems or other access issues.
