IMHO definately autovivify > > * @foo[$idx] := $var; > my @bar = @foo; > $var = $new_var; > # @foo[$idx] and $var are now $new_var, but @bar is unchanged, right? Yes, I agree. But we do need a way in the middle. Right now we have: @bar := @foo; # array container aliased, so all nested containers are shared @bar = @foo; # array structure duplicated, elem containers duplicated but no way to say all the elements are the same, but the structure isn't. Maybe this works, but I don't think so since assignment isn't an operator, but a syntactic construct (i think): @bar >>:=<< @foo; But anyway, were you to do that you could say: pop @bar; @foo's last elem still exist $bar; # @foo's first elem *is* changed -- () Yuval Kogman <[EMAIL PROTECTED]> 0xEBD27418 perl hacker & /\ kung foo master: /me dodges cabbages like macalypse log N: neeyah!
