Unnecessary, I think. I want
$x =:= @y
to tell me whether the reference in $x is to the same array as @y.
$x = 42; $a = \$x but false; $b = \$y but blue;
$a =:= $b ???
If it's true, then the =:= operator is pretty useless -- two things that are =:= to each-other can have very different semantics. If it's not, then there needs to be some other way to tell. $$a =:= $$b feels sane to me. So does $a == $b.
I generally don't like it when things half-smudge important differences. Either there should be no difference between a reference and a referent, or there should be. We shouldn't try to hide important truths. (This is why I don't like CGI.pm's HTML generation, for example -- it makes you feel like you don't need to know HTML, when you do.)
