You get that because you didn't provide a __str__() method in your
class.  As i said in my other message,   posix.stat_result  is providing
that capability for your debugging convenience.  There's no requirement
to provide it, but that's why the difference.

I haven't discovered why sometimes the type output shows type instead of
class.  There are other ways of defining classes, however, and perhaps
this is using one of them.  Still, it is a class, and stat() is
returning an instance of that class.
