False positive for B019

[nmrtv]

After the latest update, there are false positives for B019 on regular methods:

[jpy-git]

The lint is working correctly:

flake8-bugbear/tests/b019.py

Lines 72 to 103 in 0069532

	# Remaining methods should emit B019
	@functools.cache
	def cached_method(self, y):
	...
	@cache
	def another_cached_method(self, y):

	@functools.cache()

Here's a great video on why this is advised against 😄

IMO the lint message is very misleading though. it says class methods meaning methods on a class (which is pretty much the definition of a method) and probably leads to confusion with classmethods which have a very specific meaning. Will update the lint description to make it clearer 👍

(p.s. in the future it's best to copy code into issues rather than a screenshot as it saves having to re-type it out when triaging)

Actually, I don't have this problem in my code, because the class itself is a singleton. Thank you for description clarification. At least it will not be confusing why it's ignored.
