title: Angular double-curly expressions as an array
body: <p>I have <code>vm.someVal = []</code> which holds multiple <strong>true/false</strong> values like <code>vm.someValue[true, true, false]</code>. Then I pass <code>vm.someVal</code> to another directive via scope and render it inside brackets <code>{{vm.someVal}}</code>. </p>
  
  <p>My question is how can I check if <code>vm.someVal</code> is true or false? For example if <code>vm.someValue[true, true, true]</code> I want to activate ng-disabled but no matter if <code>vm.someValue[true, true, true]</code> or <code>vm.someValue[true, true, false]</code> or even <code>vm.someValue[false, false, false]</code> it want make <code>{{vm.someVal === true}}</code> true. </p>
