in thread Using map to create a hash/bag from an array
Why not use for in this example, since you're not really transforming @items into a new array (common use of map), but rather just performing an action for each value in @items (common use of for).
$bag->{$_}++ for @items; # instead of map {$bag->{$_}++} @items;
