If that's the case, and you can call the $self->Parent::DESTROY to save the child data, why not undef the parent's data at the same time, and add if defined around the untie?

That way when the DESTROY method gets called for the parent, it finds that the data is undefd, and does nothing.

Alternatively, always untie the parent's data first, then the child's, again testing defined and that should get you round the problem.

Not sure if either of those methodologies are the best, though.

Hope that helps
