[GitHub] [arrow-datafusion] alamb commented on pull request #3700: Fix `DataFrame::with_column` to handle creating column names with a period

   You can't use `col` with a qualified name (with a `'.'`)
   
   Does it work if you use 
   
   ```rust
    Expr::Column(Column {
                           relation: None,
                           name: "f.c".into(),
                       })
   ```
   
   instead of `col("f.c:)`
   
   ?
   
   
   If so we should probably offer an alternate to `col` that doesn't try and parse the relation that is not as wordy 🤔
