That's great!

What about type constraints? We should also have this information.

Shouldn't this return a collection of IReturnType?

I'm also wondering if IClass.BaseTypes should now be a list of
IReturnType instead of a list of String, since base types can now have
generic arguments.

Yes, changes in the language bindings should be included in the patch to
avoid breaking the build when it is committed.

Isn't a custom implementation of ICompletionData or
ICompletionDataProvider enough for what you want to do?

That would be awesome.

Thanks,
