Example Code

import time
from asyncer import asyncify, runnify


def sync_generator(): # generator with different long sync blocking code between yields
    for i in range(10):
        time.sleep(5) # random long sync blocking code
        yield i

async def main():
    async for i in asyncify(sync_generator)(): # requires an object with __aiter__ method, got coroutine
        print('->', i)

runnify(main)()

Description

I love asyncer and use it in several of my projects. It would be great to be able to use asyncify not only for functions, but also for generators, which are essentially the same functions, but with multiple returns.
