instanceof appears to fail when initializing resources based on a dependency

I'm guessing I just don't know what I'm doing and you aren't supposed to declare a resource from a dependency, but it seems as though _check_instance_type is failing erroneously.

> python demo.py

type(i): <class '__main__.Inheritor'>
isinstance(i, Interface): True
