I think it should be
But I see the point now. As UNIVERSAL is the parent of every object (blessed reference) and it implements method 'isa', every beast that know how to call isa method must be an object. Update: No, $r->can('isa') won't work (as I mentioned in the other reply) because if $r is not blessed, it will die on 'unblessed reference' error. UNIVERSAL::can($r,'isa') is real solution. Update2: Even if I do refcheck, situation is the same. I just cannot call any method on non-blessed reference, not even the can() method. Consider $r={}; you cannot do $r->can() because $r is not blessed. And that is what I want to know, if $r is blessed or not. I know that it is a reference. Catching a die exception with eval is TIMTOWDI, but it does not look good to me :-) In reply to Re: Re: Is reference blessed?
