    # The default_status plugin accepts a block which should
    # return a response status integer. This integer will be used as
    # the default response status (usually 200) if the body has been
    # written to, and you have not explicitly set a response status.
    # The block given to the block is instance_execed in the context
    # of the response.
    #
    # Example:
    #
    #   # Use 201 default response status for all requests
    #   plugin :default_status do
    #     201
    #   end
