IMHO definately autovivify

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

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[0]; # @foo's first elem *is* changed
