Hi Peter,
You probably sholdn't be doing this. Keys, whether in a hash or a database table, are
primary references. They should not be modified after insertion. *They are not
data*. They are program structures. Insert the key into a hash exactly in the form by
which you would like to later reference it. Any modification operations should take
place only on the values.

Probably just as well. Is there some context where you anticipate having to repair
broken keys after the fact?
