Exactly!
Classes and structures are conceptually different despite
of the fact that they share common notation.

I would suggest also to disable following:

struct mystruct {
   int myfield;
}

mystruct *pms = new mystruct;
mystruct ms;

pms.myfield = 1; // this must be an ERROR!
(*pms).myfield = 1; // this is OK
ms.myfield = 1; // this is OK
