Offhand, I'm not sure of finding this from pure Perl, though it's theoretically very easy from XS. You might try weak references in 5.6.0 and later, though (see Scalar::Util). Otherwise, matts has a good article on Proxy Objects that can solve this problem.

I'd probably use weak references, if I were you.
