... why can't you fake a closure?...

Sorry, but I don't even begin to see how to fake a closure? And how would you unfake it?

As long as you control the creation/modification/deletion of the hash keys and their values, ...

What hash? Why use a hash and how would that save memory if you do the Tie::RefHash thing of storing the smashed and unsmashed references?

If you do the RefHash thing, you don't need to do any controlling--once you delete the (value) reference, Perl takes care of the rest. But trading a hash for an array is not going to save memory.

Examine what is said, not who speaks.
Silence betokens consent.
Love the truth but pardon error.
