That only gives you trees not DAGs - you can't do fan-in (there's no way to "share" let bound names).

Isn't this fan-in?

let A = select * from tbla

let B = select * from tblb

let C = select * from A join B

Think about what tbla and tblb can be - hint they can only be globals (ie actual tables)
