[preview] FURB118 can be unsafe for methods #13829
Description
If you run with preview set, then the FURB118 check makes an unsafe replacement, you can see me rolling back the change wntrblm/nox@a91dbe2 to make the tests pass, the difference in behavior can be shown with this MWE:
>>> class A:
... pass
...
>>> A.__eq__ = lambda a, b: a == b
>>> A() == A()
Traceback (most recent call last):
File "<python-input-5>", line 1, in <module>
A() == A()
File "<python-input-4>", line 1, in <lambda>
A.__eq__ = lambda a, b: a == b
^^^^^^
File "<python-input-4>", line 1, in <lambda>
A.__eq__ = lambda a, b: a == b
^^^^^^
File "<python-input-4>", line 1, in <lambda>
A.__eq__ = lambda a, b: a == b
^^^^^^
