This package is a port of Python's built-in functools.lru_cache function
for asyncio. To better handle async behaviour, it also ensures multiple
concurrent calls will only result in 1 call to the wrapped function,
with all awaits receiving the result of that call when it completes.

Note: python3-async-lru is held back at version 2.0.5 on Slackware 15.0
(later versions require Python >= 3.10.)
