Well, if you are the developer of the library in question this is one way to
solve it. But in my case, this is really a 3rd party library that I want to
access. And I can do so with .NET language, but no can do with Ipy. You
mentioned explicit cast to IPerson. I think this is the language problem in
python, since Python does not support interfaces. Thus, code

explicit_cast = IPerson(objectInQuestion)

throws an exception NoneType yada yada. Am I missing something here?

Thanks,
 Miha.
