the latter by the way is what more or less Dallas's code already do. So I agree
with Magnus that is far from true that it's wasted effort ... What changes is
that the model observes the compenent instead of having the componenet take
care of directly updating the model.

It should be noted that under this approach unless one knows that no model is
attached to comp, is not guaranteed that this works:

L=['a',...]
comp.items=L

# later
L.insert(0,)
comp.push('items')

unless set({items = }) for a list change the a preexisting list in-place...

Otherwise the above idiom to be model-agnostic under this approach should be:

comp.items.insert('items',...)
comp.push('items')

regards.
