New changeset 46c9b34f31b8 by Ethan Furman in branch '3.4':
Issue20467: clarify __init__'s role
Simeon Visser added the comment:
Is it worth clarifying that __init__ can return a value but only the value
None? The following won't raise a TypeError:
class O(object):
def __init__(self):
return None
Admittedly the return None is the default behaviour but people may attempt

initialiser. Specifically it says As a special constraint on constructors, no
value
