Thinking about it a bit more, this makes sense because an 
interface is not necessarily an Object - it might also be a C++ 
class, or a COM object, or maybe even a slice into another vtbl 
if an Object implements multiple interfaces (not completely sure 
about the latter, I'd have to read some source, but it seems 
logical to me).
