public struct AssociativeBinaryOperator : Hashable

AssociativeBinaryOperator is an associative binary operator, such as +, *, AND, etc.

Use it with the joined(operator:) method. For example:

// SELECT score + bonus + 1000 FROM player
let values = [
    scoreColumn,
    bonusColumn,
    1000.databaseValue]
Player.select(values.joined(operator: .add))
