Would I be correct in guessing that your stringified reference comes out of a hash key? If so, you may want to have a look at Tie::RefHash. Otherwise, just create a hash table mapping pointer strings back to their original objects, as tye suggests.

If, however, by resurrecting, you mean reclaiming an object that was deleted by garbage collection (ie. refcount went to 0), this would be a very dangerous and unwise thing do, for reasons that are fairly obvious.
