ties are slow so no problem using a custom class.

And you only implemented the lookup.

I don't think it's worth making this core like they did for Py3, but having a well documented module on CPAN seems more efficient than writing, documenting and testing own code.

I'm a big fan of lazy data structures and having such a tool in the box always opens the path to new uses cases.

At least this way seems appropriate if one of the chained hashes is itself a tied structure.
