It would be nice to have derived properties that are cached within one request. That is, computed once on demand, but then cached, but not persisted.

Of course, a problem may be that the dependencies of the property are updated during the request by an action, making the cached value inconsistent.

Other than that problem, this would reduce a lot of ugly code doing this manually in various ways.
