Summary: return val in __init__ doesn't raise TypeError in new-style
Initial Comment:
returning a value (other than None) from __init__ is
supposed to raise TypeError. This only works for
old-style classes.

This has been fixed for 2.4.1 where a RuntimeWarning is
raised and in 2.5.0a where a TypeError is raised.

This should be modified to report eventual failure and added
