[GitHub] [arrow-datafusion] Dandandan commented on issue #1468: Remove `Alias` from `Expr`

   Hi @jackwener .
   
   The idea is that any expression within DataFusion receives a name, so the nodes in a LogicalPlan use the `NamedExpr` type. The name in this type is either the alias in the expression if any or the generated name, so it doesn't need to be optional.
