This is not that much of science fiction.
get commands can be used as derived tables within selects.
For ex: one can do the following to get this result:
>>create table if not exists "finance" (a int);
--- SQL operation complete.
>>select left(b, 10) from
+>((select * from (get tables in schema sch) x(a))
+> union all
+> (select * from (get users) x(a))) z(b)
+>where b like 'finance%';
