I think the ticket from @crepererum was trying to say that formatting
`Expr`s with `{:?}` (the Debug Impl) is lossy as it isn't in normal Rust style
like
```rust
Expr::InList(
InList { expr: .. }
)
```
Instead, the debug formatting is more like SQL style `IN (x, y)`.
Thus, the idea here is to change the `Debug` impl to be the normal Rust
style, and leave the `Display` impl the SQL style
However, given that Debug and Display, on the main branch, are currently the
same, there will be some places that use the `Debug` style (e.g. `{:?}` that
really should be using the `Display` style, such as the Hash Join output).
Previously this didn't matter because the Debug and Display styles are the same
