I don't know if there isn't any way such an optimization would be possible in certain cases, but it's only useful in certain contexts so probably wouldn't be worth it to implement it into perl itself.
I guess I assumed it did this optimizing because it can't detect nested assignments in TIEs. I assumed it went right to the nested reference. Since it appears to hit every key, I am a bit perplexed as to why it cannot catch nested stores and retrieves, but that's a different problem for another day.
