+ * sql/objects.lisp: Have :target-slot return of list of lists rather
+ than a list of cons pairs to be conformant with CommonSQL.
+ Make :target-slot much more efficient by using a SQL inner join
+ statement and just requiring one SQL query. Add :retrieval :deferrred
+ to target-slot joins. Add placeholder for update-objects-join.
+ * sql/classes.lisp: Add :inner-join and :on slots to sql-query class
+ and process them for query output-sql.
