Mypy v1.10.0 errors out when functools wraps a method

[davidbrochart]

Bug Report

mypy v1.10.0 gives the following error, while it was working with v1.9.0:

test.py:13: error: Missing positional argument "self" in call to "__call__" of "_Wrapped"  [call-arg]

To Reproduce

# test.py

from functools import wraps

class Foo:
    def f(self):
        pass

class Bar:
    @wraps(Foo.f)
    def f(self):
        pass

bar = Bar()
bar.f()

mypy test.py

Expected Behavior

There should be no error.

almost certainly due to #16942

I also hit this in a few places. Here's the relevant upstream bug python/typeshed#10653

Workaround I used:

from typing import TYPE_CHECKING

class Bar:
    def f(self):
        pass

    if not TYPE_CHECKING:
        f = wraps(Foo.f)(f)
