trait Rewrite extends Expression with Unevaluable

Expressions that should be rewritten eagerly. The rewrite must be able to be performed without knowing the datatype or nullability of any of the children.

In general, rewrite expressions should extend this trait unless they have a compelling reason to inspect their children.
