It's also a "for instance" where inline creation of variables is useful. As
in:

 select id1 = nextval(somesequence)
 insert into tbl (id...) values (id1...)
 select id2 = nextval(somesequence)
 insert into tbl (id...) values (id2...)
 select id3 = nextval(somesequence)
 insert into tbl (id...) values (id3...)
 select id1, id2, id3;

Or returning multiple result sets...

 insert into tbl (id...) values (nextval(somesequence)...) returning new.id;
 insert into tbl (id...) values (nextval(somesequence)...) returning new.id;
 insert into tbl (id...) values (nextval(somesequence)...) returning new.id;
