Proposal for computed properties in Dart. Whenever `firstName` or `lastName` changes, I want `fullName` to also dispatch a change event. This'll be very useful for binding a read-only property in WebUI. Right now, I have to write some ugly boilerplate to get this to work. Ideally there'd be a way to set this up through metadata.
// Assumes that we're using mdv_observe
// Verbose way
class Person extends ObservableBase {
@observable
String firstName;
@observable
String lastName;
