- * *Warning*: this library is experimental, and APIs are subject to change.
- *
- * This library is used to observe changes to [Observable] types. It also
- * has helpers to implement [Observable] objects.
- *
- * For example:
- *
- *     class Monster extends Object with ObservableMixin {
- *       static const _HEALTH = const Symbol('health');
- *
- *       int _health = 100;
- *       get health => _health;
- *       set health(value) {
- *         _health = notifyChange(_HEALTH, _health, value);
- *       }
- *
- *       void damage(int amount) {
- *         print('$this takes $amount damage!');
- *         health -= amount;
- *       }
- *
- *       toString() => 'Monster with $health hit points';
- *
- *       // These methods are temporary until dart2js supports mirrors.
- *       getValueWorkaround(key) {
- *         if (key == _HEALTH) return health;
- *         return null;
- *       }
- *       setValueWorkaround(key, val) {
- *         if (key == _HEALTH) health = val;
- *       }
- *     }
- *
- *     main() {
- *       var obj = new Monster();
- *       obj.changes.listen((records) {
- *         print('Changes to $obj were: $records');
- *       });
- *       // Schedules asynchronous delivery of these changes
- *       obj.damage(10);
- *       obj.damage(20);
- *       print('done!');
- *     }

-/**
- * Converts the [Iterable] or [Map] to an [ObservableList] or [ObservableMap],
- * respectively. This is a convenience function to make it easier to convert
- * literals into the corresponding observable collection type.
- *
- * If [value] is not one of those collection types, or is already [Observable],
- * it will be returned unmodified.
- *
- * If [value] is a [Map], the resulting value will use the appropriate kind of
- * backing map: either [HashMap], [LinkedHashMap], or [SplayTreeMap].
- *
- * By default this performs a deep conversion, but you can set [deep] to false
- * for a shallow conversion. This does not handle circular data structures.
