My bad for not knowing the limitation of the tool.
But I have no control over what version of the tool my application will encounter in the wild. I expect my application to run on any reasonably current Perl installation (old versions or not). I don't expect old versions of Storable to completely dump on a version change without some kind of backward compatibility armour built in from the get go. The fact that this is addressed in newer versions of Storable does not fix the already broken world that has been created around it.
I know I will never trust Storable to use it again. If I could, I'd vote it off the 'Perl core' island.
