The point is that it won't work in this way:

   $a = [ $ustring => $value ];
   foreach ($a as $key => $v) {
       $key->ustring_method();
   }

but one needs something along the lines of

   $a = [ $ustring => $value ];
   foreach ($a as $key => $v) {
       Utring::fromHashCode($key)->ustring_method();
   }

which likely looses object identity.

It works but is not really nice :-)
