Re: round-robin on varying sequence

How about chucking the $index and rotating the array (shift and push) every time you get an element (which is now always the first)?

remove is now as trivial as it ought to be:

sub remove {
    my %del = map { $_ => 1 } @_;
    @items = grep { not $del{$_} } @items;
}

Unless I'm missing something, this doesn't help. You still need to track an index so that you know where to insert items (now via a splice) for `add_item()`. Once you've rotated the list, you can no longer simply append to the end. --Dave	[reply] [d/l]
