contract Oddity() {
    /**
     * Transfer
     *
     * An asset transfer is permitted ONLY when the number of recipients
     * is ODD.

    function transfer() {
        /* Set (total) number of (transaction) outputs. */
        int numOutputs = tx.outputs.length;

        /* Calculate oddity flag. */
        int isOddity = numOutputs % 2;

        /* Validate oddity flag. */
        // NOTE: An even number of outputs, eg. Two (2) or Four (4)
        //       will automatically FAIL!
        require(isOddity == 1);
