Duck Typing [message #1839091]

I have a language that requires duck typing.

interface Itf {
  attrFromInterface
}

type A implements Itf {
   attrFromType
}

So given a reference of type "Itf" the attribute attrFromType shall also be visible.

I know how to access the index, but in the index there is not enough information to know who implements this interface Itf.

The question is: how do I solve this? Loading all the types in the scope provider seems to be a bit heavy (though it would not kill us in our use case as we don't have that many types). However, I have seen that the IEObjectDescription have the possibility to attach "user data". Would that be a sensible approach to attach the implemented interface in the IEObjectDescription for all the types?
