Will it be simpler if we refactor the `AttributeReference` that not to
compare the `nullable`, `dataType` or `name`, but `exprId`? If in that case,
then we might remove both `AttributeSet`, `AttributeMap` etc.
Says:
```scala
case class AttributeReference(exprId:String=ExprId)(name: String ...)
```
I don't think we can stop people to write code likeï¼
···
val exprs: Seq[Expression] = ...
exprs.toSet.contains(otherExpression)
···
