Add an option to run an asyncio event loop automatically

Experimenting with asyncio righ now is a pain. If I want just to use aiohttp to make a get request, I need to do:

import asyncio
import aiohttp

async def main():
    content = await asyncio.get('http://foo.com').content
    print(content)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

Compare to doing the same with requests:

import requets
print(requests.get('http://foo.com').content)

I wish ptpython would have an --asyncio option which starts an event loop with the shell and run any command in it.

So my example with aiohttp would become:

$ ptpython --asyncio

Then:

import aiohttp
print(await asyncio.get('http://foo.com').content)

I talked with an iPython dev, he provided me with a %magic_command which open a bloc that does just that. Since ptpython doesn’t have this concept, wrapping could work, but then you need to give it access to the variable of the previous scope, which mean you need to copy local(), pass it to the functions, and merge it to the new locals() dict.

wait. does https://bugs.python.org/issue37028 mean we can use top level await in ptpython with python 3.8 without any change?
