While "tie" in Perl allows tying to an arbitrary object, the class in question must support this in it's implementation of TIEHASH, TIEARRAY or whatever. Tie::ToObject provides a very tie constructor that simply returns the object it was given as it's first argument. That way the side effects of calling $object->TIEHASH are avoided.
