Something like this:

   $a =3D getFirstArrayName();
   $b =3D getSecondArrayName();
   if ($$b instanceof ArrayObject) {
       $$a =3D clone $$b;
   } else {
       $$a =3D $$b;
   }

   $b[1] =3D 0;

well, the same as above. not pretty, but that's a safe fallback when =
type inference is not available.
