S-SQL and nested joins

Hello,
Is there an S-SQL expression which will produce nested join expressions
like this one:
select * from table_1
inner join table_2
inner join table_3 on table_2.c = table_3.d
on table_1.a = test_2.b;
I know I can do this:
(:select '* :from 'table-1
:inner-join 'table-2 :on (:= 'table-1.a 'table-2.b)
:inner-join 'table-3 :on (:= 'table-2.c 'table-3.d))
which produces a chained join expression:
(SELECT * FROM table_1
INNER JOIN table_2 ON (table_1.a = table_2.b) INNER JOIN table_3 ON
(table_2.c = table_3.d))
However, these chained join expressions behave differently than nested ones
when mixing different types of joins, and I need the behavior of the nested
expression. I tried this:
