--- Comment #1 from Nikolay Sivov bunglehead@gmail.com --- This make sense, but this should handle a case when there a no documentation strings, in the typelib or in some custom ITypeInfo implementation. I suspect it still has to return generic "Object" for such cases.
Are you planning on working on this further, and sending a fix?
