[sv-ec] RE: mantis item 2848

The same issue exists for structs and enums defined in interfaces.

Subject: [sv-ec] mantis item 2848

I filed a mantis item today regarding virtual interfaces which can get assigned interfaces containing class declarations.
I think it should be illegal to traverse through such virtual interface to a class handle declared in the interface if its
class datatype is also in the interface declaration.
The datatype of the virtual interface select expression cannot be statically determined by the elaborator.
ex:
interface ifc;
   class C;
   int i;
   endclass
     C ch;

endinterface // ifc

module top;

   ifc ifc1();

   ifc ifc2();

   virtual interface ifc vi = ifc1;

   initial begin
      vi.ch = new(); // is this legal
      $display(vi.ch.i); // is this legal?
      vi = ifc2;
      $display (vi.ch.i);
   end

endmodule // top

Comments?
