  Suppose I have a new-style class which uses a property() call to define a
  setter:
  class C(object):
  def __init__(self):
  self.a = 5
  def set_a(self, val):
  self._a = val
  def get_a(self):
  return self._a
  a = property(get_a, set_a)
  pylint complains that self._a is initialized outside of __init__. It would
  be nice if it could figure out that C.set_a is a valid place to initialize
  self._a. (I realize this may well not be a trivial request.)
