Operator missing?

Привет! in PHP we have a set of comparison operators going like $a == $b (has same value) $a === $b (has same value and type) shouldn't we have also something like $a =&= $b (is same instance)? Maybe we already have it and I just don't know about it. Is that so? Because of the copy/reference mechanism it would really be helpful in order to check one's work in referencing objects. пока Альберто Киев @-_=}{=_-@-_=}{=_-@-_=}{=_-@-_=}{=_-@-_=}{=_-@-_=}{=_-@-_=}{=_-@ LoRd, CaN yOu HeAr Me, LiKe I'm HeArInG yOu? lOrD i'M sHiNiNg...
