Better still (fewer confusing parentheses):

    a =
        b ?
            c ? d : e
        : f ?
            g ? h : i
        : j;

You can’t avoid the parentheses, but this, too, can be improved:

    (setf a
        (cond
            (b
                (if c d e)
            )
            (f
                (if g h i)
            )
            (t
                j
            )
        ) ; cond
    )
