False positive on E1102 (not-callable) for methods called prev or next

[mathieui]

Steps to reproduce

(failing CI job on non-minimal code)
It took me a while to isolate a minimal use case, from my repeated testing:

• There is a special case, in any object, for prev() and next()
• It is only the case if the typing module is imported

Given a file test.py:

import typing

class MyClass:
    def __init__(self):
        pass

    def next(self):
        pass

    def prev(self):
        pass

    def toto(self):
        pass

    def placeholder(self):
        self.prev()
        self.next()
        self.toto()

Current behavior

Result of pylint -E test.py:

************* Module test
test.py:17:8: E1102: self.prev is not callable (not-callable)
test.py:18:8: E1102: self.next is not callable (not-callable)

Expected behavior

No error.

This seems to be related to #3970 and possibly #3595

[mathieui]

Indeed. I was mostly focused on the prev() which did not appear in my search before submitting the issue, but it certainly looks like a duplicate of both.

@mathieui i will close this issue as it seems to be a duplicate of at least #3970.
