in reply to Object and tied hash all at once?
Do you have access to (i.e. are you writing) Class::Whatever ?
If so, define Class::Whatever as a subclass of Tie::StdHash,
you can use the hash capabilities plus whatever else you add to the new class, including e.g. methods.package Class:whatever; @ISA = (Tie::StdHash)
