class ServiceObject

  def self.call(*args)
    new(*args).call
  end

  def call
    raise NotImplementedError
  end

  def perform
    call
  end

end

module Car
  class CalculatePrice < ServiceObject


    def initialize(foo)
      @foo = foo
    end

    def call
      # do something
    end

  end
end
