Re: reference as key to hash

To present the interface of a hash while not actually being a hash requires a feature called "magic". tie is a specific form of this magic, but not the only one. For example, %ENV is magical, but isn't tied.

It's possible to overload hash dereference, but I don't see how that would help here even if you were using a hash reference and not a hash.
