Ignore my last post - I was being a numpty (serves me right for trying to work whilst looking after 4 kids!). Yes, you are right, om wants you to pass the var itself.
This is all about composing components in om, which I have run into myself and don't have a particularly elegant answer. I did think about passing the delegate to the wrapper via opts, or pass a builder into the decorator's opts, but I have no idea what will happen with om's state-tracking. Maybe it will work, no idea. Alternatively you could use multi-methods here - pass in the delegate's state to animate and have animate pass that state on (if needs be) to a multi-method? Similar to how professor-view and student-view are handled in the tutorial. Sorry, I am just not familiar enough with om to help here, and I will be very interested to know the answer.
