Convert an async method to a synchronous one.

import asyncio
import functools
from typing import Any, Coroutine

loop = asyncio.new_event_loop()

    Convert an async method to a synchronous one.

    Example:

        async def some_async_method(x, y): ...

        result = syncify.run( some_async_method(1, 2) )

    Args:
        async_coroutine ():

    return loop.run_until_complete(async_coroutine)

Thanks for your answer @mikeckennedy, long and slow running tasks are important to consider.

I had a preference to high-level APIs because I was planning to teach this approach (syncify) but with the least possible complexity.
