fix: functions without 'return' are not cached

Reproducible code sample

import asyncio

from cashews import cache

cache.setup("mem://")


@cache(ttl="10m")
async def get():
    print("Start!")
    await asyncio.sleep(2)
    print("End!")
    # return "foobar"


async def func():
    await get()
    await get()


asyncio.run(func())

Expected behavior

Functions without ‘return’ must be cached. The same as Python’s ‘functools.cache’ decorator works.

@AIGeneratedUsername Thanks for you input, I on the same side with you. And you mentioned case where prefer to do not cache None, and I thought that is is more safer behavior. And now I think that I was wrong.

I’ll fix it

Thanks - I enabled it, I am not familiar with it -let’s try
