Ah ha. Interesting. I did wonder about that after reading something in the goat book about similar behaviour from
badly written classes you couldn't inherit from.
Shame because the module is very good functionally, the author
Sherzod hasn't been around for a long time according to the logs, so looks like I'm on my own with a lovely opportunity to write a storable class from the top on my own at last :()
Thanks for your thoughts Simon.
