A simple gist demonstrating how Ruby looks up module methods when they've been included in a class

includes_module.rb

module Engine
 
  def run
    puts "GRRRRRRRRR"
  end

end

class Vehicle  

  def run
    puts "I'm a thing that moves!"
  end

end

class Car < Vehicle 
  include Engine
  
  def run 
    puts "I'm driving!"
  end
  
end
 
myCar = Car.new
puts myCar.run
