yeah, if we don't document everything :))) Would you consider moving both into a unit test? Have one locally, could
send it to you ..

Also a minor quirk as to the naming: it should not name it "permutation" because it isn't from the perspective of the
list change: the notification is a "replace". Btw, the pattern in the listener (of collecting up additions/removals) is
a bit smelly - will fail as soon as you get disjoint additions (on the bright side: they don't happen in the current
implementation of ObservableList but are allowed to), just something to keep in mind :)
