… POD Three bugs fixed: 1. Handle::remove_child() left curr_pos and curr_child pointing at stale data after removing a child node. Now resets both to undef. 2. Node::value() used `defined $value` which prevented setting a value to undef. Changed to `@_ > 1` to match key()'s pattern — any value including undef, 0, and "" can now be set. 3. The otraverse() method's POD heading incorrectly said "traverse" (duplicate of the real traverse heading). Fixed to "otraverse" with accurate documentation.
