Hi Jochem,

Yes. The following should work:
interface IFoo {
   public function method();
}

trait TFoo {
   public functin method() {
      echo "Hello World!";
   }
}

class CFoo implements IFoo
{
   use TFoo;
}

This would be fine.

I don't see any sence in it. Why should one generalize an interface of a
trait?
