You could use Tie::RefHash which preserves the dereferencability of the hash key references (by storing them in a parallel array if I recall correctly.

Or you could use Devel::Pointer to unsmash the numbers from the keys back into usuable references. This requires that you remember what type of reference that you smashed in teh first place. Use with care :)

In the absence of evidence, opinion is indistinguishable from prejudice.
