[issue35040] functools.lru_cache does not work with coroutines

[Andrew Svetlov]

Andrew Svetlov <andrew.svetlov at gmail.com> added the comment:

A coroutine detection is a relatively slow check.
I don't think we need to do it in `functools.lru_cache`.

There is a specialized asyncio compatible version: https://github.com/aio-libs/async_lru
Please use it.
