When accessing a functools.cached_property through the class, mypy incorrectly treats it as a Callable.

Bug Report

When accessing a functools.cached_property through the class, mypy incorrectly treats it as a Callable.

To Reproduce

from functools import cached_property

class A:
    @cached_property
    def value(self) -> int:
        return 1

    @classmethod
    def name(cls) -> str:
        return cls.value.attrname

Expected Behavior

mypy should know that A.value is a cached_property, not a function.

Actual Behavior

error: "Callable[[A], int]" has no attribute "attrname"  [attr-defined]

Environment

• Mypy version used: 2.3.0
• Python version used: 3.12

Start by running the issue's cached_property reproduction with mypy 2.3.0 and trace how class access to functools.cached_property is inferred. The fix is complete when A.value is recognized as a cached_property rather than a Callable, allowing attrname access without an error; add a regression test for this example if the test location is identified.
