alamb opened a new issue, #2347:
URL: https://github.com/apache/arrow-datafusion/issues/2347

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   
   The datafusion prelude includes many helpful functions for constructing `Expr`s such as `lit`, `col`, etc: https://github.com/apache/arrow-datafusion/blob/master/datafusion/core/src/prelude.rs
   
   I often find myself needing to `use Expr` as well, which for some reason is not included in the `prelude` but would be more convenient if it were. 
   
   **Describe the solution you'd like**
   add `Expr` to prelude so instead of 
   
   ```rust
   use datafusion::logical_plan::Expr;
   ```
   
   People can just do 
   
   ```rust
   use datafusion::prelude::*;
   ```
   
   or 
   
   ```rust
   use datafusion::prelude::Expr;
   ```
   
   **Describe alternatives you've considered**
   Not doing it
