[New-bugs-announce] [issue11428] with statement looks up __exit__ incorrectly

[benrg]

New submission from benrg <benrudiak at gmail.com>:

class MakeContextHandler:
  def __init__(self, enter, exit):
    self.__enter__ = enter
    self.__exit__ = exit

with MakeContextHandler(lambda: None, lambda *e: None): pass

In 3.1.3 this worked; in 3.2 it raises AttributeError('__exit__'), which appears to be a bug.
