[Vala] notify for synthetic properties?

[Michael Gratton <mike vee net>]

Hey people,

Say you have a GObject with a synthetic property, the value of which 
depends on some other value, e.g.:

> public string value {
>     get { return entry.get_text(); }
>     set { entry.set_text(value); }
> }
>
> private Gtk.Entry entry;

You want to want to get notifies when the synthetic property changes, 
which is obviously dependent on the value being used.

So you can manually add handlers for the dependent value and call 
notify_property("value") when it changes, or you can use GObject 
bindings. But both of these suck since they add code cruft that is off 
somewhere far away from the declarations, and that makes it hard to 
maintain and understand what is going with the values.

Is there a nicer way to do this in vala?
