Any syntax with a let operator to name stuff or a lambda abstraction.

>>cha42+(OP)
That only gives you trees not DAGs - you can't do fan-in (there's no way to "share" let bound names).

>>almost+e8
Isn't this fan-in?

let A = select * from tbla

let B = select * from tblb

let C = select * from A join B

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