Good point. You can't. There's no binding for Closure/CClosure currently.

I'd suggest to add "new Closure.for_callback (owned CCallback callback);"
Defining a new CCallback like Callback but with has_target=true (apparently
inconsistent in glib). The ClosureNotify can be gracefully casted to
DestroyNotify. Evan?
