Imagine following situation:
 <div *ngFor="let d of dm; first as first">
    <span
      [ngClass]="{ cSmall: !first, cGray: !first, cTab1: !first }"
    >
      {{ d }}
    </span>
  </div>
All these CSS-Classes cSmall, cGray, cTab1 are depended on !first.
Can I avoid unnecessary repetitions within:
{ cSmall: !first, cGray: !first, cTab1: !first }
I've alredy tried { [cSmall,cGray,cTab1]: !first } with no success :)
