[issue7555] Wrong return value of isinstance() function

[Mark Dickinson]

Mark Dickinson <dickinsm at gmail.com> added the comment:

While I agree it's confusing, I think this is working as designed.  The 
problem is coming from the circular import.  If you add a "print id(ss)" 
between the definition of class ss and the "if __name__ == '__main__'" 
you'll see that ss ends up being defined twice.  s is an instance of one 
of the ss classes, but not the other.
