Description

The async-lru project provides a port for Python's built-in functools.lru_cache function for asyncio.

The same rules apply here with respect to garbage collection on instance methods. As this package is maintained by aio-libs it might be worth considering extending this rule to apply to uses of this decorator.

Contributor guide

Research direction
Examine the existing B019 rule implementation in flake8 bugbear to understand how it detects instance method decorator issues, then analyze the async lru package's decorator interface to adapt the rule accordingly.
