Self-properties would make it easy to observe a List as a mutable IObservableList, a Set as an IObservableSet, and a Map as an IObservableMap.  Additionally we could make a self-property IValueProperty for observing an Object as an unmodifiable IObservableValue.

In the former 3 cases, doSet<List|Set|Map> methods would just cast the property source to a List, Set or Map, and apply the diff to it.  In the latter, doSetValue() would be silently ignored.

The doGet<List|Set|Map> methods should clone the source object so that diffs can be computed appropriately (since the observables just cache whatever collection is returned instead of cloning it--otherwise we end up computing an empty diff every time).

Something like this would also satisfy the use case in bug 213848, I think
