title: How to check if scope is isolated?
body: <p>Is somehow possible to check whether angular scope is isolated or not, having the scope only?</p>
  
  <p>I know, that isolated and not isolated scopes have different prototypes. However these prototypes are private in angular and cannot be easily accessed. Checking the prototype name seems quite dirty approach.</p>
  
  <p>Any better idea?</p>
