Hey, I already knew that!

The bad thaw is there on purpose, to show that after such failure Storable will stop being able to freeze.

It appears to be that something goes wrong in the internal state of Storable when you feed a bad value to 'thaw', that prevents it from working again.

I've tried unloading and reloading after the bad thaw by doing:

delete $INC{'Storable.pm'};
require Storable;
[download]

But that only replaces the subroutines and doesn't clear the internal state, which is my guess from the barrage of warnings this gives when run under 'use strict'.
