DeprecationWarning: "@coroutine" decorator is deprecated #276
Description
Module cached_property.py, function wrapper, declared in line 42, uses decorator @asyncio.coroutine.
It seems that the asyncio @coroutine decorator is deprecated since Python 3.8.
Please use async def instead.
Source code should be modified to look like:
def _wrap_in_coroutine(self, obj):
@wraps(obj)
async def wrapper():
future = asyncio.ensure_future(self.func(obj))
obj.__dict__[self.func.__name__] = future
return future
return wrapper()
