[sv-ec] base interface class references (Mantis 1356)

Consider the following:

     class base#(parameter p = 1);
     endclass

     class derived extends base#(3);
     endclass

Assume I then have something like:
     derived der = new;
     base #(3) b = der;

Per 8.5, it is legal for me to reference "der.p".

Will the same thing be legal for a interface class?

     interface class base#(parameter p = 1);
     endclass

     class derived implements base#(3);
     endclass

     derived der = new;
     base #(3) b = der;

Is "b.p" a legal reference here? "derived" definitely
does not inherit (or implement) the parameter "p".
Conceptually, "p" is not part of derived at all, so is it
legal to reference it via a base interface class variable
whose handle is an implementing class? If "b.p" is
legal, is "der.p" legal?

Gord.
