explicitly putting parenthesis to forward arguments

super.rb

module A 
  def say_hi(a,b,c)
    puts "Hi, from [A] module. Numbers - #{a} #{b} #{c}"
  end
end

class B
  include A

  def say_hi(a,b,c)
    puts "B is saying Hi.. "
    
    # explicitly putting parenthesis - this will send no arguments
    super()
  end
end

b = B.new
b.say_hi(1,2,3)

#output
B is saying Hi..
