S-SQL and nested joins

[Eli Naeher]

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:
