* All expressions need to have this getter for complicated type-related reasons.

* import { type Expression, type OperationNode, sql } from 'kysely'

* }

* }

||||
* ```
|
||||
*
|
||||
* The getter is needed to make the expression assignable to another expression only
|
||||
* if the types `T` are assignable. Without this property (or some other property
|
||||
* that references `T`), you could assing `Expression<string>` to `Expression<number>`.
