No :-(
Because:
a) Perl-level functions can't be called during the middle of cloning,
as the internal state isn't yet consistent.
b) Cloning of objects can't be done at the Perl level, it has to be done
at the C level, eg making sure that memory is allocated from the correct

c) It would be very expensive to call a Perl function for each object
