Note that there is a similar issue with cached generators.
>>> from functools import *
>>> @lru_cache()
... def g():
... yield 1
...
>>> list(g())
[1]
>>> list(g())
[]
I am not sure that it is safe to detect awaitables and iterables in caching
decorators and automatically wrap them in re-awaitable and re-iterable objects.
But we can add explicit decorators and combine them with arbitrary caching
decorators. For example:
@lru_cache()
@reiterable
def g():
yield 1
