[phobos] Questionable unit test in std.functional

At the very bottom of std.functional, there is this unit test:

    /* test for linkage */
        struct S
            extern(C) static void xtrnC() {}
            extern(D) static void xtrnD() {}
        auto dg_xtrnC = toDelegate(&S.xtrnC);
        auto dg_xtrnD = toDelegate(&S.xtrnD);
        static assert(! is(typeof(dg_xtrnC) == typeof(dg_xtrnD)));

Is there any reason why dg_xtrnC and dg_xtrnD should have different types?
As far as I can tell the calling convention of the function should be
completely hidden.
