          ip_protocol 'tcp'
          from_port ref!(:my_from_port)
          to_port ref!(:my_to_port)

        -> {

          to_port ref!(:foo_to_port

Or you can add to an exsiting thing
  
    resources(:some_resource) do
    properties do |current_properties|
      current_properties.policies += _array(
        -> {
          policy_name 'my_fancy_policy'
          policy_document do
            statement _array(
              -> {
                effect 'Allow'
                action %w(someaction:*)
                resource '*'
              }
            )
          end
        }
      )
    end
