EmberJS computed `and` negation

I have a class with properties:

import { and, not } from '@ember/object/computed';

EmberObject.extend({
    a: false,
    notA: not('a'),

    b: true,
    c: true,
    d: and('b', 'c', 'notA')
});

So d relies on the negation of a.

Is there a notation to do something like d: and('b', 'c', '!a') so that I don't need the redundant notA property?
