pub trait BoolExpressionMethods: Expression<SqlType=Bool> + Sized {
    fn and<T: AsExpression<Bool>>(self, other: T) -> And<Self, T::Expression> { ... }
    fn or<T: AsExpression<Bool>>(self,
                                 other: T)
                                 -> Grouped<Or<Self, T::Expression>> { ... }
}
