Hi Matt.
There is a DelayedObservableValue class which does the same thing for
IObservableValues.
I did not find something similar for lists/sets/maps.
I didn't had a look into the implementation of DelayedObservableValue,
but you might be able to adapt that for lists/sets/maps?
I also think it would make sense to have a DelayedObservableList, etc.
integrated in the databinding in the framework.
Cheers.
