That's obviously a bug in valac, however it's safe to ignore for now;
it's more a cosmetic problem than anything else. We'll fix it as soon as
we have proper flow analysis in place.

Thanks for fixing the example. Vala SVN now reports an error when trying
to define a signal in a type not deriving from GLib.Object.

The implicit namespaces are not supported in C#, that's a Vala feature.
