Hi @twalthr , I find that `expr` in `expressionDsl.scala` has done what we
want. As we can do like this: `12.expr % 'f0` or `12 * 'f0.expr`.
So do we need this PR just rename `expr` to `toExpr` ?

> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Reporter: Timo Walther
> Assignee: Jark Wu
> Priority: Minor
>
> The Table API does not support binary expressions like {{12 < 'f0}} in Scala
> DSL where the left side is a literal. Maybe this can be solved by implicits
> or at least by a {{12.toExpr}} method.
