First, the data structure you've shown isn't actually valid: $foo = { ... }; is missing a hash key, so for now I'm just going to assume $foo = { foo => ... };

Thanks - that was, obviously, incorrect. The structure does not necessarily alternate between @ and % - but I'm fairly certain that there's no AoA component anywhere (and lots of HoH structures.)

Your code works for $foo, but unfortunately not for the more complex structure - "Not an ARRAY reference" errors, unsurprisingly. I'm pretty sure it's that assumption that the next level down must be an array... as I've said, it's arbitrary depth. I appreciate your effort, though!
