**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** I am trying to implement support for the expression `EXISTS (<subquery>` and this requires having a new `Expr` variant that refers to a `LogicalPlan`. However, this is not possible because `LogicalPlan` is in the core `datafusion` crate which depends on the `datafusion-expr` crate that contains `Expr`, and therefore it is not possible to reference `LogicalPlan` from `Expr`. **Describe the solution you'd like** `LogicalPlan` and `Expr` should live in the same crate IMO so I propose moving `LogicalPlan` into the `datafusion-expr` crate. **Describe alternatives you've considered** None **Additional context** None -- This is an automated message from the Apache Git Service.
