### Is your feature request related to a problem or challenge? _No response_ ### Describe the solution you'd like According to following stackoverflow [discussion](https://stackoverflow.com/a/76403415/10554257). `Box`s can deep copy when called with `.clone()` method (according to `.clone()` implementation of the underlying type.). For `Box<Expr>` this is the case. I think this usage might be the reason of some deep stack usages seen during the planning. See related issues: TODO: Add ISSUE. I think, replacing `Box<Expr>` usages with `Arc<Expr>` under the `enum Expr` would improve performance. I am not familiar with the implications of these two approaches in other places. I wonder what community thinks about this change. Would it be better, unnecessary, etc? ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
