I'm trying to provide a tied hash interface to a C object in my XS code. The OUTPUT section of my typemap looks like 

T_TIED_HASH

        {
                SV* tie = NEWSV(0, 0);
                HV* hash = newHV();

                /* Get a blessed reference to the pointer, */

                sv_setref_pv(tie, CLASS, (void*)$var);

                /* and tie it to a hash. */

                hv_magic(hash, (GV*)tie, PERL_MAGIC_tied);

                $arg = newRV_noinc((SV*)hash);
        }

which I was expecting to return a tied HV reference. However, in my test code 
my $obj = new TiedXS(1);

ok($obj);
ok(tied $obj);

the first test succeeds, but the second fails. Ideas?
