How does this work, given that you are never changing @key and you never set $k? And doesn't $root = $root->{ $k }; just dereference rather than move the root?

Update: to answer my own questions - the previously missing line allows for the changes and the root moves because of the explicit creation of the sub-hashref. Good solution (++).
