Thanks Ben,

This isn’t something I'd seen before (god that makes me feel stupid). I've always based my code off the odd example that's dotted around and hadn’t ever done any proper reading on these new type classes.

I've done a little reading this morning and really love a great deal of the concepts, I'll be upgrading my app to this spec in the next few days.
