When an hashref is really a blessed object, I want its toString() method to be called to dump the hashref content to my result SV. Calling the object's toString() method is the task for the code I shown you.

But why do you need to go to XS and back to do that? I appreciate this is probably a simplified example but if the thing you want to serialise already has a toString method to serialise it in Perl AND you want to return this in your results SV why do that in a round about way in XS? 

sub serialise {
    my $ref = shift;
    my $str = undef;
    eval{ $str = $ref->toString };
    return $str if defined $str;
    $str = XS_serialise($ref);
    return $str;
}
