     *
     * If you are creating a custom expression, it's often easiest to use the {@link sql}
     * template tag to build the node:
     *
     * ```ts
     * import { type Expression, type OperationNode, sql } from 'kysely'
     *
     * class SomeExpression<T> implements Expression<T> {
     *   get expressionType(): T | undefined {
     *     return undefined
     *   }
     *
     *   toOperationNode(): OperationNode {
     *     return sql`some sql here`.toOperationNode()
     *   }
     * }
     * ```
