Yes, Traits are meant to be compile-time only, they are not used to introduce
typing relationships.

Yes, sure.

This is a typical pattern I would expect to see in code that uses traits.
You have an interface and then you provide a trait thats provide a standard
implementation for that interface. I would probably call the trait similar to
the interface HelloImpl or THello or so.

If that does not work, it is a bug I think.
