	# When @message is a String or an Array,
	# the return_value is set to a Sinatra-compliant
	# Array with @code being the first element and the
	# response body being the stringification of the
	# JSON stringification of @context and @message.
	#
	# If @message is a String, it is first put into an
	# array.
	#
	# If @message is neither a String nor an Array,
	# @return_value becomes simply @code.
