Thanks, @alamb. That's a good point to have `PartialOrd` on `Expr`. For the CSE use case, it would be nice if we can compare and arrange `Expr`s in some kinds of order. By doing that we can recognize `a+b` and `b+a` are the same expression. And I think it can help other things too. -- This is an automated message from the Apache Git Service.
