Setter by property: false positive warning

[vepain]

False positive description

class Foo:

  __ACLASSATTR = 0

  def __init__(n: int):
    self.__n = n

  @property
  def n(self):
    """The n getter."""
    return self.__n

  @n.setter
  def n(self, new_n: int):
    """The n setter befor @classmethod creates a warning."""
    self.__n = new_n

  @classmethod
  def a_classattr(cls):
    return cls.__ACLASSATTR

Behavior

What expected (to my mind)

no warning

Current result

Foo.n should be after Foo.a_classattr

Discussion

Because of the false positive result of mypy (see python/mypy#1465) the two warnings make the problem unfeasible.
But I think it is a great idea to keep getter and setter near to each other for the same attribute.
So let consider you have to keep setter just after the getter

I second this bug, my minimum working example is:

class LogMessage:
    @property
    def package(self) -> str:
        return ""

    @package.setter
    def package(self, value: str) -> None:
        self.bar = value

    @property
    def message(self) -> str:
        return ""

    @message.setter
    def message(self, value: str) -> None:
        self.foo = value

When I group the setters the error goes away.

Also faced this. Seems very reasonable to keep property and setter together.
