What was wrong with the UUID proposal? It sound like you abandoned that idea. I interpret it to mean create a scalar ref whose object is a unique number. Then, the dereferenced value, not the volatile address, becomes the object key.
The UUID proposal would have much less overhead than having a CLONE method repair all the dangling links in each hash.
