Hmm - no, the array isn't touched by UserDefaults at all - I read the
thread on that - interesting, and similar - but we're just using an
ArrayController here.

Perhaps Uli's vauleTransformer from the example you linked could be
useful here - to turn the Array back into into a MutableArray.

I still think it's odd that the controller appears to be altering the
class of my model's property.
