	of PyMapping_Keys because we know we have a real dict. Tolerate that objects may have an attr named "__dict__" that's not a dict (Py_None popped up during testing). test_descr.py, test_dir(): Test the new classic-class behavior; beef up the new-style class test similarly. test_pyclbr.py, checkModule(): dir(C) is no longer a synonym for C.__dict__.keys() when C is a classic class (looks like the same thing that burned distutils! -- should it be *made* a synoym again? Then it would be inconsistent with new-style class behavior.).
