FWIW, I don't think there's much to fix other than the spec since this hasn't
ever worked (DMD seems to be quite liberal in accepting attributes almost
anywhere, but it doesn't mean it enforces anything) and nobody has requested
this as far as I know. Also bug #1351 points out that export attribute doesn't
even make sense.

Mixins and composition indeed solve "is implemented with" relationship and
interfaces can be used to enforce a specific functionality.
